Waveshare Servo Driver HAT User Manual
The Servo Driver HAT is a Raspberry Pi‑compatible expansion board that uses a PCA9685 chip to provide 16‑channel 12‑bit PWM/servo control via the I2C bus. It includes an on‑board 5 V regulator, supports 6‑12 V input, and can supply up to 3 A to the servos.
The guide covers hardware connections, enabling I2C on the Pi, and provides Python 2/3 example programs for direct PWM control, Wi‑Fi remote control, and Bluetooth remote control. It also details the PCA9685 library functions and required parameters for proper servo operation. This manual is written in Chinese.
