The Raspberry Pi Servo/PWM Expansion Board is compatible with Raspberry Pi Zero, Zero W, Zero WH, 2B, 3B, and 3B+ models. It can be I2C controlled using only 2 pins and provides up to 16-channel servo/PWM outputs with 12-bit resolution for each channel (4096 scales). The board integrates a 5V regulator with up to 3A output current, allowing it to be powered from the battery through the VIN terminal. It supports standard servos such as SG90, MG90S, MG996R, and more. The expansion board also includes reserved I2C control pins, enabling seamless integration with other control boards. For added convenience, the board comes with development resources and a manual, including Python examples for Bluetooth/WiFi remote control.
