Waveshare 15275 Servo Driver HAT

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.

Features

• 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)

Ordering Info

This HAT provides 2 options for the onboard pinheader:

• Servo Driver HAT: straight pinheader, same size as the Pi Zero, convenient for integration
• Servo Driver HAT (B): right angle pinheader, make it possible to connect servos even when stacking up

Except pinheader, the PCB and all other function/properties are exactly the same.
