 Communication with the Master Controller and daughter modules is done through flat flex connecter J11 shown in <imgref pcbSchematic>​. This connector contains two serial UART bi-directional communication busses, event system GPIO pins, and a safety interlock signal. ​ Communication with the Master Controller and daughter modules is done through flat flex connecter J11 shown in <imgref pcbSchematic>​.

 +Generally with flat flex jumper cables, the cables can be folded but the bend radius should not be less that 2mm. The clearance in front of the pcb FFC connectors must be at least 0.25 inches to allow the flat flex cable to exit and bend. The distance between the FFC connector and the first bend of the flat flex cable is determined by the length of the stiffener (or backing) on the flat flex cable.
