USB Key AVR Programmer

So, you saw some AVR microcontrollers and you decided they are cute (they really are!). If you choose to work in plain C what you need is just a toolchain (you probably have some package ready for your distribution), the avr-libc library, a programming software like avrdude and a hardware programmer!

While you can freely download all the software you need, including the source code, for the programming hardware you have to choose between buying a commercial programmer (either from Atmel or some third party) and building your own.

What I’m publishing in this post is my version of the popular USBasp, an open source USB AVR programmer design from Thomas Fischl.

My version is a USB key-like design, using many SMD parts and a very small PCB. You can take it with you everywhere!
