Qwiic Shield for Arduino
Note: The shield includes R3 Arduino headers, but they are not pre-soldered onto the board, so
some assembly will be required when putting the shield together. The image below shows the shield
after the header has been soldered to the PCB to.
The Qwiic Shields have 4x Qwiic connect ports, all on the same I
2
C bus. Logic level converters are
included for the Qwiic connect port’s SDA and SCL lines so you do not have to worry about using
the Qwiic system with 5V (or 3.3V) devices.
In addition to this, a large prototyping area is included. As shown in the image below, the Qwiic
shield for Arduino has a few neat features such as a few 3-by-1 rails to help with prototyping.
