1.2 Target market and purpose of the board
The boards from the OLinuXino family are easy to setup and powerful. It is possible to use them in
almost any application as a host board. They are suitable for embedded programming enthusiasts,
Linux and Android gadget fans (they can just use the board as a media center or fully functional
Linux-PC for instance) and also professionals (since its low cost makes it very good solution for
application-orientated embedded systems). The main usage of the board is software embedded
development without the urge of understanding perfectly the hardware.
The strong points of the boards are the processor speed, the small form factor and the low price-toproductivity ratio.
Customers have full access to the technical documentation of the board. The software is released
under General Purpose License and the board is considered open-hardware – all schematics and
board design files are available to the customer under the Creative Commons AttributionShareAlike 3.0 Unported License.
1.3 Board variants
There are two major board variants. According to the names: A10S-OLinuXino-MICRO-4GB and
A10S-OLinuXino-MICRO. The 4GB version has a built-in NAND memory suitable for the storage
of an operating system without the need of a SD card. The 4GB version comes with already
programmed Android 4.0.4 image.
The other Olimex boards with close characteristics are the ones with A13 and A10/A20
microcontrollers. The A13 boards feature a generation older processor but since they have been
longer on the market they have better Linux support. The A10 boards feature the bigger (than A10s)
processor of the Allwinner A10 family. The A20 boards feature the new dual core processor and
pack exceptional (for an embedded device) computing speed.
Additional Linux support and features are added overtime. The Linux support is a work in progress
and you should not expect full Linux support after the initial volume of such boards have become
available on the market. If you are in a hurry consider the older OLinuXino designs (which have
almost everything supported, have examples available and so on).

CHAPTER 2: SETTING UP THE OLINUXINO BOARD
2. Introduction to the chapter
This section helps you set up the OLinuXino development board for the first time. Please consider
first the electrostatic warning to avoid damaging the board, then discover the hardware and software
required to operate the board.
The procedure to power up the board is given, and a description of the default board behavior is
detailed.
2.1 Electrostatic warning
OLinuXino is shipped in a protective anti-static package. The board must not be exposed to high
electrostatic potentials. A grounding strap or similar protective device should be worn when
handling the board. Avoid touching the component pins or any other metallic element.
2.2 Requirements
In order to set up the A10S-OLinuXino-MICRO optimally one or more additional items may be
used. They might be generally placed in three categories:
Required - items that are needed in order to achieve minimum functionality;
Recommended – items that is good to have in order to be able to interact with the most important
of the features of the board;
Additional – items that provide additional access or expand the features of the board.
Required items:
- USB type A to USB mini cable – to connect to a personal computer; used for powering the board
and uploading new Android image to the NAND memory (if your board has 4GB NAND)
- Input device – either a mouse/keyboard or touchscreen LCD
- Output device – either HDMI cable + HDMI-enabled monitor/screen/projector; or OLIMEX LCD
(TS) display + 40-pin CABLE-IDC40-15cm; or USB-SERIAL-CABLE-F + personal computer (for
Linux and/or Android debugging)
- SD card with compatible image – if you have the board version with NO additional NAND
memory you will need to use one of the images available.
Recommended items:
- External USB hub – to split the USB_HOST mounted on the board; you need that to connect more
than one USB device
- External power supply unit – 5V DC, 5W required (5V @ 1A) – for optimal power
- USB-SERIAL-CABLE-F – for Android/Linux debugging on UART0
- CABLE-IDC40-15cm – LCD cable for LCD_CON connector
Additional items include:

A13-LCD7 – low-cost 7'' LCD display with optional touchscreen component - 800 x 480
A13-LCD10 – low-cost 10'' LCD display with optional touchscreen component – 1024 x 600
2.3 Powering the board
There are two possible ways of powering A10S-OLinuXino-MICRO-4GB – via external supply
providing 5V DC (!) at the power jack or via the USB_OTG connector. Note that the board
consumes around 300mA of current at 5V when there are no peripherals connected to the USB host,
so make sure the power supply is able to provide at least 500mA before plugging. Depending on
your preferred way of powering you might need additional hardware.
The preferred way of powering board is via the PWR jack with 5V DC with a power of 5W (e.g.
5Vx1A). This will make the board fully powered and able to power all the peripherals connected to
it.
Note that when powering the board from the USB_OTG, the power provided might be insufficient
to also power a bigger LCD connected to the LCD_con. However, this power option is capable of
driving the board when using external display connected to the VGA connector.
Note that there are no means provided to power the A10s board from a battery.
The typical consumption of A10S-OLinuXino-MICRO-4GB is between 200mA and 320mA
depending on the current load. While the board is in stand-by mode it consumes 200-220mA.
If the board has entered power-down state you can bring it back without restart using the
PWR_BUT.
For the European customers we sell two power supply adapters, please check chapter 2.2. We also
sell USB OTG to USB type A cables if you lack such.
The default username/password combination for the default Linux image on the SD card (if
purchased) is: root/olimex.
Note that it is normal that when the board is powered some integrated circuits might appear hotter
than others. This is perfectly normal for some chips – for instance – voltage regulators and the main
processor.

2.4 Button functions and NAND image restore in Android
The following buttons represent functions in the Android:
PWR_BUT – used to perform software turn off, software turn on and
HOME – shows the home screen; note that HOME is also used to enter bootloader mode for
firmware update
ENTER – to select a choice
MENU – brings up the main menu
VOL+ – increases the volume
VOL- – lowers the volume
BOOT/REC – depending on the selection of UBOOT/REC jumper this button might serve either
as the trigger used to enter bootloader mode (for NAND update via the USB_OTG connector) OR
as a recovery button (“wake up” in Android).
It is not recommended to disconnect the power supply (either the USB or the power jack) before
turning off the Android from the either the menus or by holding POWER system written on the
NAND.
2.5 Prebuilt software
The 4GB board-variant comes with Android 4.0 ready to use. The default settings of the software
are followed.
How we have installed the software? We have configured an Android image with settings suitable
for A10S-OLinuXino-MICRO. Then using LiveSuit tools we uploaded the image to the board via
the USB OTG. The image is available for users to try and tweak the settings. The images can be
downloaded from the wiki article at: https://www.olimex.com/wiki/A10S-OLinuXino-MICRO-4GB
The board variant without NAND needs an SD card with bootable OS – Android or Linux. There
are ready images available for download at the A10s wiki article at Olimex's web site.
To repair the image on NAND re-upload it following these easy steps:
1. Run LiveSuit (can be found in the wiki article for A10s and A13)
2. Disconnect the power supply and USB cable.
3. Place jumper BOOT/REC in BOOT position.
4. Press and hold BOOT/REC button, apply power supply, attach USB cable and release the
BOOT/REC button.
5. LiveSuit will detect the bootloader and will ask which file to program to the NAND flash.
6. Wait till upgrade succeeds as shown below:

CHAPTER 5: CONTROL CIRCUITY
5. Introduction to the chapter
Here you can find information about reset circuit and quartz crystals locations, the power supply
circuit is discussed.
5.1 Reset
The board has no hardware reset. The reason behind that is the memory problems using such a
strategy causes. When the NAND memory performs read/write operation and the user resets the
board this might cause NAND corruption.
The board should be turned off the standard OS menu (that might be invoked by holding POWER
button) and after the choice is confirmed it is safe to be disconnected from the power supply unit.
5.2 Clocks
25 MHz quartz crystal Q1 is connected to pins 46 and 47 of the RTL8201CP chip (the same chip
controls the Ethernet).
24 MHz quartz crystal Q2 is found at pins U20 and V20 of the A10s microcontroller.
5.3 Power supply circuit
The power supply is handled mainly by AXP152 power management system, an Allwinner chip that
goes together with the A10s processor. It is mounted on the board but since it is relatively hard to
find we also sell it separately.
The power supply circuit of A10S-OLinuXino-MICRO requires input supply of 5V. The minimum
amperage suggested is 1A, and this threshold may raise if using a lot of devices on the USB-HOST
(via external hub), a lot of GPIOs and the LCD_CON.

CHAPTER 6: CONNECTORS AND PINOUT
6. Introduction to the chapter
In this chapter are presented the connectors that can be found on the board all together with their
pinout and notes about them. Jumpers functions are described. Notes and info on specific
peripherals are presented. Notes regarding the interfaces are given.
6.1 Communication with the A10s
The chip has a built-in bootloader for communication with computer systems via a USB cable –
suitable only for connection with LiveSuit program for firmware update. There is a second option to
connect to the board which is the male UART0 connector capable of delivering some information
on the COM port of your computer – and then use your favorite terminal program (puTTy, teraterm,
etc) to receive the data/send commands. You can use USB-SERIAL-CABLE-F with the UART0
interface allowing you to connect to an USB port.
6.1.1 USB-OTG communication (NAND firmware repair/update)
The main way of communicating with the firmware of A10S-OLinuXino-MICRO is via the USBOTG connector.
You will need a software tool “LiveSuit” and a newer firmware image if you wish to upgrade/repair
the firmware. The simple steps for upgrading/repair the firmware via the bootloader are:
1. Download, install and start LiveSuit
2. Hold down “BOOT/REC” button on the board
3. Connect the board to the computer via the USB-OTG
5. Release “BOOT/REC” button
6. You will be asked for drivers, point manually the driver installer to the LiveSuit folder which
contains drivers for the bootloader
7. Choose the image you have prepared or downloaded
8. Update and don't disconnect the board until the LiveSuit program confirms the update is
complete
There are different flavors of the same distribution depending on whether you want to use 50Hz
HDMI or 60Hz HDMI or 7'' display or 10'' display etc. You might need to change the configuration
files inside (depending on your current setup) the SD card (explore the SD card and make sure the
correct, corresponding your needs, “script.bin” is placed in the first SD card partition; overwrite the
original one).
Those images and the software required might be download from the wiki page:
https://www.olimex.com/wiki/A10S-OLinuXino-MICRO

A10S-OLinuXino-MICRO user's manual
6.1.2 UART0, UART1, UEXT interface
The UART0, UART1 and UEXT interfaces might be used for COM communication. The UEXT is
typically used for connecting additional modules, but it can be used for debugging purposes also.
You can use our USB-SERIAL-CABLE-F (in the case of UART1 you can either use USB-SERIALCABLE-M, or USB-SERIAL-CABLE-F + jumper wires) for debugging.
Consider table below when connecting the USB-SERIAL-CABLE-F according to the wire color
code. The RX line of the cable (GREEN wire) should go to TX line of the target board; the TX line
of the cable (RED wire) should go to the RX line of the target board. The BLUE wire should go to
the target's GND line.

The JTAG debug connector and options haven't been thoroughly tested – you are welcome to send
us feedback and your experience with this interface.
6.2 SD card connectors
There are two SD card connectors on this A10s board. The now common microSD card connector is
located on the top of the board, near the HDMI connector. However, due to popular demand, there
is also an SD/MMC card connector located on the bottom of the board.
Both SD slots might be used simultaneously – there is no data multiplexing lines. For instance – one
of them might be used for booting the OS, the other – for saving data.
As a general precaution be careful with the SD cards you purchase. There is a big percentage of
fake cards due to the low effort required to counterfeit popular brands and the big demand for SD
cards worldwide. When in doubt – try the same operation with another card from another brand.
Olimex sells microSD cards with Linux or Android images, that have been tested – please refer to
chapter “2.2 Requirements”. Of course, if you already have a big enough microSD card you can
download the official Linux image from the wiki pages: https://www.olimex.com/wiki/A10SOLinuXino-MICRO.
When removing the card, please make sure that you release it from the connector by pushing and
NOT by pulling the card directly (this can damage both the connector and the microSD card).
6.2.1 SD/MMC1 slot
SD/MMC1 slot is the “smaller” microSD card slot, located on the top of the board.
This slot is typically used for booting the OS, due to the larger capacities of the microSD cards
(compared to SD or MMC cards). It is suggested to have an SD card with a proper Linux/Android
image especially if you have ordered a version of the board without NAND memory. It is also
Page 18 of 36

Additionally, there are the WP and CP switches that are responsible, respectively, for sensing
whether the card is locked for reading and whether there is a card inserted.
Note that there is multiplexing on pins A11 and B12 of the A10s processor. The SD/MMC1 and the
UART1 share the same data pins. This means it is not correct to use the UART1 interface and the
SD/MMC1 interface at the same time.

Signals marked with * are multiplexed with either a peripheral device or another connector. Ensure that the multiplexing is handled
properly on software and/or hardware level (else there would probably occur wrong levels, loss of data, etc).
The LCD connector is suitable for a number of Olimex displays and touchscreen panels with
different native resolution – the smallest available is the 4.3'' one called A13-LCD43TS with native
screen resolution of 480x272, through the 7'' one named A13-LCD7 with 800x480, to the
1024x600 10.1'' A13-LCD10.
IMPORTANT:
To use Android with display or resolution different than VGA and 800x600 (default settings) you
need to upload new Android image to the board. These images are available here:
https://www.olimex.com/wiki/A13-OLinuXino (using an operating system - NAND flash).
Since the configuration in the Debian images is set to VGA and 800x600 (default settings) you
would need to change a configuration file in the main partition of the SD card. Detailed information
and download locations for the script files might be found at:
https://www.olimex.com/wiki/index.php?title=Configuration_of_hardware_in_the_debian_image.
