Build Piconomic Atmega128 development board by yourself
First of all, I have ordered to make PCB by using a milling-drilling plotter. Of course, I could make the board by myself, but I wanted to save some time and nerves in case of errors. After one week my board was shipped to me: Then I bought all parts needed. One thing that didn’t go well was that I couldn’t get capacitors and resistors in SMD packages 0603, so I used 0805 to lie on the side.
