Keyestudio Micro bit PCA9685PW Motor Driver Expansion Board Shield For Micro bit

The Keyestudio Micro:bit PCA9685PW Motor Driver Expansion Board Shield is a versatile add-on designed to expand the capabilities of your micro:bit. Ideal for South African students, educators, and hobbyists building robotics projects, this board simplifies motor control and sensor integration. It provides a robust platform for driving motors and connecting various peripherals without exhausting your micro:bit's IO pins.

Efficient motor control architecture

The board combines a PCA9685PW chip and a TB6612FNG driver chip to manage your motors. By using the PCA9685PW to control the TB6612FNG, it conserves valuable IO port resources on your micro:bit.

Dual DC motor driver

The onboard TB6612FNG motor chip allows you to control both the rotation direction and speed of two DC gear motors. This makes it perfect for building small mobile robots and wheeled projects.

Built-in RGB lights and buzzer

This expansion shield integrates two standard RGB lights, four WS2812 RGB lights, and an onboard buzzer. These features allow you to easily add visual effects, status indicators, and audio feedback to your creations.

Dedicated sensor interfaces

The board features dedicated P2.0 interfaces for connecting an ultrasonic sensor, an infrared sensor, and a tracking sensor. These connections make it simple to build obstacle-avoiding or line-following robots.

Onboard level conversion

It includes a TXS0108EPWR level conversion IC interface, providing a stable 5V output voltage. This ensures safe and reliable communication between your 3.3V micro:bit and 5V peripherals.

Power and physical specifications

The board accepts an input voltage range of DC 7V to 12V and outputs 5V. It measures 92mm by 64mm by 15mm, with a lightweight bare board weight of just 41.8g.
