MCD6A: ESP32 TB9054 Motor Controller

project image


This library is for custom dual channel, H-bridge, brushed DC motor controller with encoder quadrature decoder, current sensing and onboard ESP32 micro-controller for control, automation and robotics application. It can also support external H-bridges drivers connected with ESP32 devkit with/without encoder. It may required certain modification.

Application

Robotics application such as ground robots, self-balancing robot and automation application etc.

Specification

  • Motor Driver : Dual channel, H-bridge.
  • Control Input : PWM with frequency from $1-10\ khz$.
  • Operating Voltage : $\mathrm{V_{BAT}}\ =\ 4.5\ \text{to}\ 28\ V$, $\mathrm{V_{CC}}\ =\ 4.5\ \text{to}\ 5.5\ V$, $\mathrm{V_{DDIO}}\ =\ 3.0\ \text{to}\ 5.5\ V$.
  • Operating Temperature : $Ta\ =\ -40\ \text{to}\ 125^o\mathrm{C}$
  • Protection : Stop output for supply under voltage, over current, over temperature.
  • Sensing : High voltage side output current monitoring.
  • Encoder Decoder : Onboard quadrature decoder of dual channel digital encoder for motor rpm measurement with onboard power supply to encoder sensor.
  • Interfacing : USB serial interface of micro-controller with computer for two-way communication firmware upload, control, communication and sensors data streaming.
  • Control : Onboard PID control of motor RPM with onboard speed and current sensing.

Hardware Support

  • Custom Controller using ESP32.
  • ESP32 devkit with separate H bridge motor driver.
