- When i saw simpleavr's implementation of usbtiny on attiny45 , i thought it would be cool if i make a kit version of this with a minimal form factor. Then i designed a PCB and sent for first prototype. Later on i thought, if i want to sell this, it would be much cooler ,and more suitable with "Open Source Hardware" concept, if i bring this project one step ahead. So i tried to fit anything extra to the device and this project came out.
- usbtiny compatable AVR programmer in minimal form factor with all through hole components
- Computer controllable (via USB) additional features:
- 4 channel digital input / output
