SparkFun Servo pHAT for Raspberry Pi

DEV-15316

 

The SparkFun Servo pHAT for Raspberry Pi allows your Raspberry Pi to control up to 16 servo

capabilities, this PWM HAT saves the Raspberry Pi's GPIO pins, allowing you to use them for other

purposes. The Servo pHAT also adds a serial terminal connection, which will allow you to bring up a

Raspberry Pi without having to hook it up to a monitor and keyboard. We have provided a Qwiic

specifically for connecting to the Sphero RVR.

Power to the SparkFun Servo pHAT can be supplied through USB-C connector. This will power

either the servo motors only, or power the servo motors as well as the Raspberry Pi that is

connected to the HAT. We switched to USB-C to allow you to bring more current to your servos than

ever before. This USB-C connector can also be used to hook up the Pi via serial port connection to

avoid having to use a monitor and keyboard for setting up the Pi. To supply power only to the servo

power rail (and not the Pi's 5V power rail), you just 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 avoid damage to power sources.

Each of this pHAT's 16 servo motor pin headers has been spaced out 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 (not yet tested on the Raspberry Pi 4).

Note: This HAT includes headers to connect to a Raspberry Pi, so there is no soldering required to

get up and running quickly.
