Documentation notice: This technical documentation was independently rewritten from an archived supplier source. Check technical details and commands against the product version and manufacturer documentation before use.
Summary
The module extends the Raspberry Pi Pico family with I2C-controlled driving of up to four DC motors via a TB6612FNG dual H-bridge and a PCA9685 PWM driver.

Technical overview
- Control is via I2C; five address jumpers allow 32 different I2C addresses.
- Integrated 5 V regulator provides up to 3 A output current; operating voltage at VIN is 6–12 V, logic level 3.3 V.
- PCA9685 generates 12-bit hardware PWM for motor speed control.
- TB6612FNG is a dual H-bridge driver with high efficiency and low heat generation.
- Unused Pico pins are broken out for easy extension.
- Dimensions: 65 × 56 mm, hole diameter 3.0 mm.
- For MicroPython: flash firmware via the RPI-RP2 drive entry, then run PCA9685.py; demo spins motors A/B forward at full speed (2 s) and reverse at half speed (4 s).
- For C/C++: create project in VSCode with the pico-vscode extension, compile and flash the .uf2.
- For Arduino: install Arduino-Pico Core in the IDE, load example project and upload.
- Two demos available: C and MicroPython, each with identical motor behavior.
Commands and examples – verify before use:
sudo apt upgrade thonny
Notes and version constraints
- No explicit command lines besides the Thonny update command in the source; other commands are not specified.
- Exact pinout and jumper configuration must be taken from the schematic; only general statements are given here.
- Version-sensitive steps (e.g., Thonny v3.3.3 on Windows, pico-vscode v1.87.0+) require manual verification of the local environment.
- The source contains no prices, stock levels, certifications or warranty information; such details must not be added.
