SparkFun Qwiic Shield for Thing Plus Hookup Guide
Introduction
The SparkFun Qwiic Shield for Thing Plus provides an easy-to-assemble way to add the SparkFun Qwiic
ecosystem to any development board with the Thing Plus Footprint. This shield is also compatible with the Feather
Footprint so you can add Qwiic functionality to any development board that uses the Thing Plus or Feather
Footprints! It connects the I C bus (GND, 3.3V, SDA, and SCL) on your Thing Plus to four SparkFun Qwiic
connectors. The Qwiic ecosystem allows for easy daisy chaining so, as long as your devices are on different
addresses, you can connect as many Qwiic devices as you'd like.

Required Materials
To follow along with this tutorial, you will need an Arduino development board with the Thing Plus footprint. This
includes the all variants of the SparkFun Thing Plus boards and many other Thing Plus-compatible boards! Here
are a few of the compatible boards:
You will also need some headers to solder to both your Thing Plus and Qwiic Shield:
SparkFun Thing Plus - ESP32 WROOM
WRL-15663
SparkFun Thing Plus - Artemis
WRL-15574
SparkFun Thing Plus - SAMD51

Hardware Overview
Qwiic Connectors
The Qwiic Shield for Thing Plus has four Qwiic connectors on it. The two on the edges are the standard horizontal
connectors and the two in the middle are vertical connectors.
I C Jumper

communications protocols in use today.

This jumper is a little different than our normal I C pull up jumpers as it is open by default. The jumper only needs
to be closed if your slave device does not have pull up resistors. Essentially all SparkFun I C breakouts come with
pull up resistors on them so if you are using a Qwiic I C device or another SparkFun I C device, you can most
likely leave it open. When closed, the SDA and SCL lines are pulled to 3.3V by 4.7K resistors. If you have never
worked with solder jumpers before, check out this tutorial for some tips and tricks for working with them.
Board Dimensions
The shield measures 2.00in x 0.90in (50.8mm x 22.86mm) and has four mounting holes that fit a 4-40 screw.

Hardware Assembly
All you need to get started using the Qwiic Shield for Thing Plus is to solder whichever headers you choose to the
shield and, if necessary, to your Thing Plus (or compatible board). If you have never worked with an Arduino
Shield before or need some tips, our Arduino Shields Tutorial provides detailed instructions on how to assemble
and use them.
Once you have soldered headers to your shield and connected it to your Thing Plus, it's time to start connecting
Qwiic devices! Below you can see the Qwiic Shield connected to a SparkFun Thing Plus - SAMD51 using the
Feather Stackable Header Kit along with a couple of Qwiic Devices chained to it.
