PCB for PedroBot

I am currently developing a PCB for PedroBot. I think this might interest other robot designers.

This is a Pcb running with an AtMega644p or AtMega1284p to offer more memory for the program, so I added the bluetooth module, a lithium polymer battery charger as well as a step-up booster 5v. A sound sensor, and obviously the usb port in order to program via the Arduino IDE.

At the outputs, there are 16 free to connect servos or other devices. I also awarded 4 plugs with keycords for the led matrix, the ultrasonic sensor, the Buzzer and the switch.

For the time being, it is in development. I am open to all proposals and remarks.
