X-MR-B3RB-PDB Schematics
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.
