Description :

SparkFun Servo pHAT for Raspberry Pi allows controlling up to 16 servo motors via I2C connection, saving Raspberry Pi’s GPIO pins.
I2C capabilities, serial terminal connection, and Qwiic connector for easy interfacing with I2C bus.
Power can be supplied through the USB-C connector, and can power both the servo motors and Raspberry Pi or only the servo motors by cutting a small trace on the isolation jumper.
Power protection circuits to avoid damage to power sources.
16 servo motor pin headers spaced out to the standard 3-pin servo pinout (ground, 5V, signal) for easy attachment of servo motors.
The same size and form factor as Raspberry Pi Zero and Zero W, can also operate with a regular Raspberry Pi.

Features:

16 PWM channels, controllable over I2C
Qwiic connector
4-pin RVR header for connection to Sphero RVR
USB-C connector
40-pin GPIO header for connection to Raspberry Pi
CH340C USB Serial SOIC16
Updated logic level conversion circuitry
Power protection circuits
