Servo Driver HAT for Raspberry Pi 16-channel with I2C
This Waveshare HAT generates up to 16 PWM signals for servos with the PCA9685 and is controlled via I2C with only two pins. It fits the 40-pin header of the Raspberry Pi and also works with the Jetson Nano. A built-in 5 V regulator with up to 3 A supplies the servos, either from the Raspberry Pi or via the VIN screw terminal with 6 to 12 V.
Important: By default, the servos are powered from the 5 V of the Raspberry Pi. With powerful servos such as the MG996R, this voltage drops and the Raspberry Pi restarts. In that case, according to Waveshare, remove the 0 Ω resistor on the board and power the servos via VIN with 6 to 12 V.

Recommended Accessories:
- Waveshare Micro Servo 9G / SG90
- Waveshare Micro Servo MG90S with Metal Gear
- Waveshare High Torque Servo MG996R 10kg/cm
- Servo Cable Servo Extension Cable AWG26 300mm
Features:
- 16 PWM channels with 12-bit resolution
- Control via I2C, only 2 pins used on the Raspberry Pi
- I2C address 0x40 by default, adjustable via solder jumpers A0 to A4, so several HATs can run on the same bus
- 5 V regulator for the servos up to 3 A, supply via VIN 6 to 12 V possible
- Standard servo connectors for SG90, MG90S, MG996R and similar
- I2C control pins brought out at the side, usable for other controllers
- Python examples for Raspberry Pi and Jetson Nano
Application Examples:
- Robot arms, hexapods and robots with many servos
- Pan and tilt heads for cameras
- Dimming LEDs via PWM
