Servo Driver HAT for Raspberry Pi, 16-Channel, 12-bit, I2C


Waveshare 15275 – Servo Driver HAT for Raspberry Pi, 16-Channel, 12-bit, I2C Interface, Straight Pinheader

Needless to say, the Raspberry Pi is powerful enough in most cases, yet it’s not that good at providing precise PWM output. You may have tried to control a robotic arm or a hexapod walker by using the Pi, but finally get frustrated due to the limited number of PWM outputs and the jittering servo.


Now you get a new option to bring your ideas to life, we prepare this useful Servo Driver HAT for you.

Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano
I2C controlled, using only 2 pins
Up to 16-Channel servo/PWM outputs, 12-bit resolution for each channel (4096 scales)
Integrates 5V regulator, up to 3A output current, can be powered from battery through VIN terminal
Standard servo interface, supports common used servo such as SG90, MG90S, MG996R, etc.
Reserved I2C control pins, allows to work with other control boards
Comes with development resources and manual (examples in python like Bluetooth/WiFi remote control)
