SparkFun Qwiic Shield for Thing Plus Hookup Guide
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 I2C 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.

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:
SparkFun Thing Plus - ArtemisWRL-15574
SparkFun Thing Plus - SAMD51DEV-14713
The Qwiic Shield includes a set of stackable headers to fit the Thing Plus footprint but you may also need some headers to solder to your Thing Plus. Or if you would prefer to use another header type for your shield assembly we've listed a few options below:
Break Away Headers - StraightPRT-00116
Break Away Headers - LongPRT-10158
Feather Stackable Header KitPRT-15187
Now you probably would not want the Qwiic Shield for Thing Plus if you didn't have any Qwiic products to use with it, right? Well, if you don't have any Qwiic products, the following might not be a bad place to start:

You will need some of our Qwiic cables to connect your devices to the shield. Below are a few options:
Qwiic Cable - 100mmPRT-14427
Qwiic Cable - 500mmPRT-14429
Qwiic Cable - 50mmPRT-14426
Qwiic Cable - 200mmPRT-14428
Lastly, if you want to use a non-Qwiic I2C device, these adapters help to convert it to a Qwiic connector:
SparkFun Qwiic AdapterDEV-14495
Qwiic Cable - Breadboard Jumper (4-pin)PRT-14425
Qwiic Cable - Female Jumper (4-pin)CAB-14988
You will need a soldering iron, solder, and general soldering accessories to solder the header pins to the Qwiic shields:
Solder Lead Free - 15-gram TubeTOL-09163
Soldering Iron - 30W (US, 110V)TOL-09507

How to Solder: Through-Hole Soldering
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.
This jumper is a little different than our normal I2C pull up jumpers as it is open by default. The jumper only needs to be closed if your peripheral device does not have pull up resistors. Essentially all SparkFun I2C breakouts come with pull up resistors on them so if you are using a Qwiic I2C device or another SparkFun I2C 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.
The shield measures 2.00in x 0.90in (50.8mm x 22.86mm) and has four mounting holes that fit a 4-40 screw.
All you need to get started using the Qwiic Shield for Thing Plus is to solder the included stackable headers or 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 included with the shield along with a couple of Qwiic Devices chained to it.
