This is my adaptation based on Aproxx design!

I wanted to use ATMEGAS328 to make te overall project cheaper! So I picked Aproxx idea and developed my owne PCB!

This project is still under development, I what to order the board and teste it myself before submitting the link to the store order!

I will be using DirtyPcb to print!

enter image description here

I added a interface to burn sketches into the ATMEGA328 with a FTDI!
