Balboa 32U4 Control Board
Balboa 32U4 Control Board
This is primarily intended as a replacement part for the Balboa 32U4 Balancing Robot, but it can also be combined with the Balboa Chassis with Stability Conversion to make your own Balboa 32U4 robot. This product consists of the Balboa 32U4 control board PCB shown in the main product picture along with the following additional parts:
- one buzzer
- jumper wires for soldering motors to the board
- two magnetic encoder discs
- one single flat and one single spring battery contact
- four 3/16″ #2-56 screws and nuts for mounting the board to a Balboa Chassis

- Forum post: Correcting the Balboa magnetometer
- Pololu forum user Jim Remington has shared a technique for compensating for hard iron distortion of the Balboa’s magnetometer. After corrections, he was able to create a compass program with a basic accuracy of ±2°, sufficient for navigating the Balboa around the room.
