LORDWORLD Motor Driver HAT PCA9685 TB6612FNG I2C 12-bit PWM 32 stackable development board

SKU CH-4NNV-32M8M

A Raspberry Pi HAT that drives two DC motors via a TB6612FNG bridge and 12-bit PCA9685 PWM, I2C addressable and stackable up to 32 boards with an onboard 5 V 3 A regulator

  • Stack up to 32 boards via 5 address jumpers
  • 12-bit hardware PWM from onboard PCA9685 chip
  • Dual H-bridge TB6612FNG driver runs cool and efficient
  • 5 V regulator delivers up to 3 A from battery VIN
  • 40-pin GPIO header fits Raspberry Pi series boards

Motor Driver HAT for Raspberry Pi

This HAT adds dual DC motor control to any Raspberry Pi board with a 40-pin GPIO header. It uses an I2C interface so the host can command speed and direction without dedicating PWM pins. The board is designed for robotics and automation projects that need reliable low-level motor drive.

Sustained operation with PCA9685 and TB6612FNG

The onboard PCA9685 generates 12-bit hardware PWM signals, offloading timing from the Pi CPU during long runs. The TB6612FNG dual H-bridge runs with high efficiency and low heating, keeping temperatures stable when motors operate continuously. A 5V regulator supplies up to 3A from a battery connected to the VIN terminal.

Stackable I2C expansion up to 32 boards

Five address jumpers let each HAT claim a unique I2C address, allowing up to 32 modules on the same bus. Reserved I2C control pins remain free for other peripherals. Projects that need more than 32 motor channels or a different bus voltage will require a separate I2C multiplexer or level-shifting solution.

Questions about this item

Does the TB6612FNG driver run hot when driving two motors continuously?

The onboard TB6612FNG dual H-bridge is described as high efficiency with low heating, so it stays cool during extended operation.

Must I already own a Raspberry Pi with the 40-pin header to use this HAT?

Yes, the board uses the standard Raspberry Pi 40PIN GPIO extension header and is designed for Raspberry Pi series boards.

Will the PCA9685 PWM chip conflict with older I2C sensors I keep on the bus?

Five address jumpers let you set a unique I2C address for each of up to 32 stacked modules, avoiding conflicts with existing devices.
