GPIO#

All of the MD controllers have two multi-purpose GPIO pins. Currently they have two functionalities:

  • Auto Brake - in this mode MDxx will automatically engage MAB Robotics’s provided braking systems via GPIO A pin, please contact us for more information in that regard

  • GPIO input - in this mode MDxx will output GPIO pin states to state register (userGpioState 0x161)

Important

The GPIO are connected directly to board’s MCU. DO NOT drive this pins higher than +5V or lower than 0V as this WILL damage the board.

Also the GPIO pins are floating so if you want to use those pins as an external function switches, do so with proper pull-up/down resistor or push-pull circuitry.
