Price range: $15.00 through $25.00

An open-source, closed-loop DC motor controller built for my DIY robot dog: CAN bus, Wi-Fi, Bluetooth and I2C on one small board that daisy-chains.

This kit contains:

  • 1x DaisyBoard
  • 1x 90 degree male and female XT30 connector set
  • 1x vertical male and female XT30 connector set
  • 1x 25V 330µF capacitor
  • 1x 25V to 5V regulator
  • 1x 20V USB-C power input
  • 1x heatsink
  • 1x 300mm JST-SH cable

Description

An incredibly feature-filled DC motor controller board that I designed for my custom quadruped robot dog. Read the whole story on the DaisyBoard build log.

Features

  • 5–24V DC input through XT30 or a USB-C port
  • XT30 power output for stacking or daisy-chaining boards
  • H-bridge motor controller: forward/reverse and full PWM range output through XT30
  • Pad for a current sense resistor of your choice
  • Two CAN bus ports (TJA1050T transceiver) for daisy-chained communication between boards, with a built-in 120Ω terminating resistor on a solder pad
  • DIP switch resistor network to set the CAN address externally (up to 16 addresses)
  • 5V level-shifted I2C port compatible with Adafruit STEMMA QT and SparkFun Qwiic
  • JST-SH 4-pin port with power, ground and two GPIO pins, plus a 3-pin header with 3.3V, ground and one GPIO
  • Built-in six-axis IMU
  • Runs on an ESP32-C3 SuperMini for Wi-Fi and Bluetooth

The KiCad files and BOM are open source, so you can also order boards yourself from a PCB assembly company; the build log has step-by-step PCBWay ordering instructions.
