SparkFun Servo pHAT for Raspberry Pi & NVIDIA Jetson Orin Nano

Product Overview

The SparkFun Servo pHAT allows your Raspberry Pi or NVIDIA Jetson Orin Nano to control up to 16 servo motors in a straightforward and uncomplicated manner via an I²C connection. Thanks to its I²C capabilities, this PWM HAT saves the Raspberry Pi's GPIO pins, allowing you to use them for other purposes. The Servo pHAT also features a serial terminal connection, allowing you to boot a Raspberry Pi without a monitor or keyboard. We have provided a Qwiic connector for easy interfacing with the I²C bus using the Qwiic system.

Power to the SparkFun Servo pHAT can be supplied through a USB-C connector. This will power either the servo motors only or both the servo motors and the Raspberry Pi or NVIDIA Jetson Orin Nano connected to the HAT. We switched to USB-C to let you draw more current from your servos than ever before. This USB-C connector can also connect your single-board computer via a serial port, allowing you to avoid using a monitor and keyboard during set-up. To supply power only to the servo power rail (and not the 5V power rail), you need to cut a small trace on the isolation jumper. Doing this allows you to drive heavier loads coming from multiple or larger servos. We've even added power-protection circuits to the design to prevent damage to power sources.

Each of this pHAT's 16 servo motor pin headers is spaced to the standard 3-pin servo pinout (ground, 5V, signal) to make it easier to attach your servo motors. The Servo pHAT is the same size and form factor as a Raspberry Pi Zero and Zero W, but it can also operate with a regular Raspberry Pi or NVIDIA Jetson Orin Nano.
