This page has details about the PCB used for the Hexbot robot. At present we are using a breadboard because we have not designed or manufactured the PCB. Here are the details regarding the breadboard.
The circuitry for the Hexbot robot is designed in Eagle CAD.
The PCB is fabricated using a third party service.
