DaisyBoard-DC: The Ultimate Daisy-Chainable Motor Controller

The DaisyBoard-DC is an open-source motor controller designed for robotics enthusiasts, makers, and engineers. Originally developed for our DIY quadruped robot, this compact board integrates I2C-controlled PID motor control, CAN bus communication, and an ESP32-C3 microcontroller—all in a tiny, stackable package.

Key Features:

Power Options: 5-24V DC input via XT-30 or USB-C.

Daisy-Chain Power & Communication: XT-30 power output allows stacking or daisy-chaining multiple boards.

H-Bridge Motor Control: Supports 24V, 13A motor control with full PWM range.

Current Sensing: Customizable current sense resistor slot.

CAN Bus Networking: Dual CAN bus ports with onboard TJA1050T transceiver.

Configurable CAN Addressing: DIP switch network allows 16 unique addresses.

I2C Expandability: 5V level-shifted I2C port (Adafruit Stemma QT & Sparkfun QWIIC compatible), plus support for SEEED Grove and non-level-shifted I2C.

Versatile GPIO: Includes JST-SH 4-pin and 3-pin headers for external peripherals.

Built-in IMU: Six-axis IMU for motion sensing.

ESP32-C3 MCU: Onboard WiFi & Bluetooth.

Easy CAN Termination: 120Ω terminating resistor with a simple solder pad.

Expandable Power Regulation: Optional solder-on 5V regulator for large daisy chains.

Compact & Stackable: Three mounting holes for flexible installation.

How It Works:

The ESP32-C3 SuperMini (included) provides processing power.

USB-C or XT-30 connectors power the board and motor.

CAN bus ports enable communication between multiple boards.

I2C ports allow integration with magnetic encoders, sensors, and controllers.

Stacked boards share power and data seamlessly.
