SparkFun Qwiic Shield for Thing Plus Hookup Guide

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.
I2C Jumper
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.
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.
