The SparkFun Servo pHAT is an add-on board for Raspberry Pi that allows easy control of up to 16 servo motors via an I2C connection. It saves GPIO pins for other uses and includes a serial terminal connection for Raspberry Pi setup without a monitor or keyboard. It features a Qwiic connector for simple interfacing, a 4-pin header for connecting to the Sphero RVR robot, and a USB-C connector for the power supply. The board has 16 PWM channels, standard servo pin headers, and compatibility with both Raspberry Pi Zero/Zero W and regular Raspberry Pi models. It also incorporates power protection circuits, updated logic level conversion, and a CH340C USB Serial chip for communication.

Package Includes:

• 1 x SparkFun Servo pHAT 

Specifications:

• The number of Servo Motors: Up to 16 servo motors can be controlled simultaneously.
• Communication: Servo motors are controlled through an I2C connection.

• Connector Interfaces:

  • Qwiic connector for easy interfacing with the I2C bus using the Qwiic system.
  • 4-pin header specifically designed for connecting to the Sphero RVR robot.

• Power Supply:

  • USB-C connector for power input. It can power the servo motors only or both the servo motors and the connected Raspberry Pi.
  • Option to isolate the servo power rail from the Pi's 5V power rail by cutting a trace on the isolation jumper.
• Compatibility: The Servo pHAT is designed to be compatible with Raspberry Pi Zero, Zero W, and regular Raspberry Pi models.
• GPIO Header: 40-pin GPIO header for easy connection to the Raspberry Pi.
• USB Serial: CH340C USB Serial SOIC16 chip for USB serial communication capabilities.
• Logic Level Conversion: Updated logic level conversion circuitry to ensure reliable communication between the pHAT and Raspberry Pi.
• Power Protection: Power protection circuits are included in the design to prevent damage to power sources.

Features:

1. Control of up to 16 servo motors: The pHAT allows your Raspberry Pi to easily control up to 16 servo motors, providing precise movement and control.
2. I2C connection: Servo motors are controlled via an I2C connection, which saves the GPIO pins of the Raspberry Pi for other purposes.
