Pi Servo pHAT (v2) Hookup Guide
The SparkFun Pi Servo pHAT provides your Raspberry Pi with 16 PWM channels that can be controlled over I2C. These channels are broken out in a header combination that is perfect for connecting servo motors. Additionally, the PWM channels can control other PWM devices as well.

Furthermore, the Pi Servo pHAT can be used for a serial terminal connection to remotely control the Raspberry Pi, without the need for a monitor and keyboard (header used by the Sphero RVR). As an added bonus, we have provided a Qwiic connector for users to easily interface with the I2C bus using the Qwiic system. Who says you can't have it all?
To get started with the Pi Servo pHAT, you will need a Raspberry Pi board with headers. There are several options that can be found under the Raspberry Pi Board product category. Additionally, we also offer these boards in various kits.

SparkFun Pro Micro - RP2040DEV-18288
Raspberry Pi PicoDEV-17829
SparkFun Raspberry Pi Zero W Basic KitKIT-14298
Raspberry Pi 3 B+ Starter KitKIT-15361
(Some, but not all of our Raspberry Pi kits include a Raspberry Pi. Be sure to double check the Includes tab of the associated product page. Additionally, the Sphero RVR kits will include this Pi Servo pHAT.).
There are a few additionally accessories that you will need to use your Raspberry Pi.
You will need an microSD Card, Power Supply, and USB-C Cable (optional) at minimum to run your Raspberry Pi. There are two options for the microSD card, a NOOBS card that comes pre-flashed with the OS need to run your Raspberry Pi or a blank SD card that can be flashed using the files and instructions from the Raspberry Pi Foundation page.

USB 3.1 Cable A to C - 3 FootCAB-14743
(To flash your own SD card, you will also want to grab a microSD USB adapter.)
Last of all, to test the functionality of the Pi Servo pHAT you will want a servo motor.
Servo - Generic (Sub-Micro Size)ROB-09065
Servo - Generic Metal Gear (Micro Size)ROB-14760
Actuonix PQ12-100-6-R Micro-ActuatorROB-18591
(Any "standard" 5V servo in our catalog should work. Keep in mind when purchasing, the continuous rotation servos behave differently from the normal servos.)
No tools are required to used this product. However, you may need a soldering iron, solder, and/or general soldering accessories to solder modify the jumpers or solder on headers to your Raspberry Pi board (if it didn't come with them).
