Schematics as per production build.

The PDB serves two main functions: 1) Takes in Battery voltage and provides FUSED RAW battery and regulated 5V power out.

2) a connector interface converter board.

Additional features include:

  • An INA226 power simple power measurement IC is used to give an indication of battery state by Current and voltage measurement.

  • The Raw Battery connectors go to other boards such as NavQPlus and MR-CANHUBK344

  • The 5V power supplies the servo and other local interfaces

  • Other connectors are provided to adapt between the B3RB motor's Hall sensor, Quatrature encoder and drive signals.

  • LED lighting via a STEMMAQT type connector also is adapted . NOTE This is NOT STEMMAQT signalling specification. But it is convenient to use the available off the shelf cabling.
