1. INTRODUCTION

CT-UNO is a Cytron version of Arduino Uno. This board combines the simplicity of the

UNO’s Optiboot bootloader (which load program faster), the stability of the FTDI and the R3 shield compatibility of the latest Arduino UNO R3 .

CT-UNO has all the amazing features Arduino UNO offer. 14 Digital I/O pins with 6 PWM pins, 6 Analog inputs, UART, SPI, external interrupts, not to forget the I2C too. The SDA,

SCL and IOREF pins which being broken out on UNO R3 are on CT-UNO too. We has also populated the ISP header pins (SPI and power). With this, CT-UNO will be compatible with all Arduino UNO's shield.

CT-UNO comes with following features:

● SMD ATmega328 microcontroller with Optiboot (UNO) Bootloader.

● USB Programming Facilitated by the Ubiquitous FTDI FT231X (more stable).

● Input voltage: DC7-15V.

● On board 1A (maximum) 5V voltage regulator.

● On board 500mA (maximum) 3.3V voltage regulator.

● 0-5V digital outputs with 3.3V compatible inputs.

● 14 Digital I/O Pins (6 PWM outputs).

● 6 Analog Inputs (Can be digital I/O too).

● ISP 6-pin Header.

● 32k Flash Memory.

● 16MHz Clock Speed.

● R3 Shield Compatible.

● TX, RX, Power, pin 13 LEDs are moved to edge.

● Utilize USB Micro-B socket.

● White PCB!

6. HARDWARE INSTALLATION

6.1 CT-UNO power supply

CT-UNO power source is either from 12V power adapter (via DC jack) or USB cable . If

CT-UNO is powered using both supply (12V adapter and USB cable) it will automatically choose power from adapter.

● CT-UNO is being powered using adapter.

● CT-UNO is being powered using USB cable.

Product User’s Manual – CT-UNO

● If CT-UNO is powered with both 12V Power adapter and USB cable, it will automatically choose power from power adapter.

6.2 Downloading bootloader firmware

CT-UNO provide ISP for user uploading Arduino Uno bootloader firmware. User can use

AVR programmer (e.g. AVR USBasp ) to upload firmware to ATmega328p.

6.3 Interface CT-UNO

● CT-UNO is Arduino Uno compatible, so it can be stacked with all Arduino UNO compatible shields. Below is example LCD Keypad shield stacked onto CT-UNO.

● This is example of wireless remote mobile omni robot that uses CT-UNO,

SHIELD-XBEE and FD04A-R2 board.

7. GETTING STARTED

7.1 Get a CT-UNO board and USB cable

You will need a CT-UNO and USB Micro B Cable to start.

7.2 Download the Arduino Environment

Get the latest Arduino IDE from http://arduino.cc/en/Main/Software .

When the download finishes, unzip the downloaded file. Make sure to preserve the folder structure. Double-click the folder to open it. There should be a few files and sub-folders inside.

7.3 Connect the CT-UNO

CT-UNO automatically draw power from either the USB connection to the computer or an external power supply. To start, just connect CT-UNO board to laptop/computer using USB micro B cable . The PWR LED (green) will light up to indicate the board are being powered.

7.4 Install the drivers

● Plug in your board and wait for Windows to begin it's driver installation process. After a few moments, the process will fail, despite its best efforts. If the driver installation succeed, it means you already use FTDI device with your computer before.

● In the case of fail, you can download the latest FTDI driver on FTDI website. Choose appropriate operating system.

( http://www.ftdichip.com/Drivers/VCP.htm

). After download is complete, proceed with the installation.

● If the driver installation succeed, you should have the COM port number for your

CT-UNO board.

7.5 Launch the Arduino IDE

Double click on arduino.exe.

7.6 Open blink example

Go to Files -> Examples -> 01.Basics

-> Blink .

7.7 Select your board

Go to Tools -> Board -> Arduino Uno .

7.8 Select CT-UNO serial port number

Go to Tools -> Serial Port -> select your CT-UNO COM port number.

7.9 Upload the program

● Now, simply click the "Upload" button in the environment. Wait a few seconds - you should see the RX and TX leds on the board flashing. If the upload is successful, the message "Done uploading." will appear in the status bar.

● A few seconds after the upload finishes, you should see the pin 13 (L) LED on the board start to blink (in orange). If it does, congratulations! You've gotten CT-UNO up-and-running.
