Pi Servo Hat Hookup Guide
The SparkFun Pi Servo Hat allows your Raspberry Pi to control up to 16 servo motors via I2C connection. This saves GPIO and lets you use the onboard GPIO for other purposes. Furthermore, the Pi Servo Shield 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.
Here’s what you need to follow along with this tutorial. We suggest purchasing a blank microSD card rather than a NOOBS ready card, since the NOOBS ready cards may not have a new enough OS to support the Pi Zero W.
No special tools are required to follow this product assembly. You will need a soldering iron, solder, and general soldering accessories.
