SparkFun Qwiic Shield Compatible with Arduino-Simple to incorporate Qwiic connect system w/ R3 footprint system I2C 4 mounting ports 3-by-1 power rails & ground buses Converts 5V-3.3V Soldering Needed

Sparkfun’s Quiic system provides a de-facto standard for I2C connections, but the board is only really compatible with Arduino Uno. I used it with Arduino Mega by soldering some pin headers onto the 5V, 3.3V, and GND, as well as the A4 and A5 data pins, which are the SDA and SCL connections on older UNOs. Be aware that the board positions labeled SDA and SCL aren’t connected to the Qwiic ports on this board (or anything really, other than the adjacent closest holes). In my application, I ran DuPont wires from the pin headers on the shield, to the corresponding header sockets on the Mega.
