Overview
1.1.
Introduction
USBasp is a USB in-circuit programmer for Atmel AVR controllers. It simply consists of an
ATMega8 and a few passive components. The programmer uses a firmware-only USB driver, no
special USB controller is needed.
Some of the key features include:
a.
Works under multiple platforms. Linux, Mac OS X and Windows are tested,
b.
Programming speed is up to 5kBytes/sec, and
c.
SCK option to support targets with low clock speed (< 1,5MHz).

Description
AVR
According to Atmel, AVR stands for nothing, it's just a name. Others say
it stands for Advanced Virtual RISC. However, the inventors of the AVR
series chips are named Alf Egil Bogen and Vegard Wollan, so you be the
judge.

Warnings
Some of the components discussed in this document are very sensitive to electrical
static discharges. The reader should take precautions to ensure that components are
protected against these discharges.
Whilst the voltages typically seen in microcontroller circuits are low, the reader
should be aware of the risk of working with electrical circuits and take necessary
precautions.

USB Type A
The USB end of the programmer connects directly into your computers USB port.
2.2.
ISP1 – 10 pin IDC
The 10 pin ISP connection provides an interface to the microcontroller. This interface uses a 10 pin
IDC connector and the pinout is shown in Figure 2

IPS2 – 6 pin SIL
The 6 pin ISP connection provides an alternative to the standard 10 pin IDC connector. The board
provides 6 holes where a single row header, polarised header or other connector can be mounted. The
pinout is shown in Figure 3.

By soldering some single row headers to the underside of the programmer board, you can have the
programmer in a form where it can easily be used on a breadboard. This is show in Figure 4 and
Figure 5.

J1 – Self Program
This jumper is used to update the firmware of the USBasp programmer. In order to update the
firmware you will need 2 programmers. One to be programmed and the other to do the programming.
2.5.
J2 – Supply Target
If this jumper is bridged, then +5V supply from the USB port will go tho the target device via the ISP
VCC connector. Disable this jumper if the target device has its own power source.
2.6.
LEDs
The USBASP programmer has 2 LEDs near the ISP2 connection. These have the following functions:
a.
LED 1 – Power
b.
LED 2 – Programmer communicating with target device
