MR-B3RB-PDB
(DRAFT)
The MR-B3RB-PDB (Power Distribution board) sits on the lower chassis and provides the following functions:
3S power input from LiPO battery or power supply with XT60 type power connector.
Regulated 5V supply for boards and servos
JST-GH Power cable connections for the NavQPlus and MR-CANHUBK344
Filtering on the power supply connectors
Optional 5V power source and termination for a CAN bus.
3-pin Dupont style PWM connector to MR-CANHUBK344 and ESC cable connector. The PWM signals connect through to the two signals (Enable and PWM) on the ESC (motor controller) integrated into the BLDC motor on the B3RB Buggy Chassis.
3-Pin Dupont style PWM connectors also provide 5V "up" to the "servo rail/PWM rail" on the MR-CANHUBK344 in order to provide power to the Steering Servo or any other RC-PWM connected devices.
2 pins for use in providing 5V to the RGB-LEDS (TBD, this is optional and power presently is supplied via a 4 pint JST-GH on the MR-CANHUBK344)
Quadrature Encoder in (custom) and out (JST-GH) connectors. In from B3RB motor, out via JST-GH to MR-CANHUBK344.
Remove Jumper from PDB
During manufacturing test, there may be a jumper on the PDB connecting + and S of the 3 pin servo header as shown below. It is very important to remove this jumper, It will NOT be used
