Description
This is a Christmas programmable development board that incorporates the ATMEGA1284P chip, an H bridge and an FTDI programmer. It is Arduino compatible, so it can be programmed with the Arduino IDE. It has 31 digital inputs and outputs, of which 6 are pwm and 8 are analog inputs. I developed this board in the EasyEDA PCB design program (https://easyeda.com/), I highly recommend it as it is very easy to use and has a lot of built-in libraries.
I am very happy that I did this as I am only 17 years old and I don't have much experience in PCB design.
