Product description
SparkFun Qwiic Shield for Arduino is an expansion board that makes it possible to connect Qwiic modules and sensors to Arduino UNO R3/R4. The board mounts on top of the Arduino UNO and connects its I2C bus to four Qwiic connectors. Built-in level shifting converts the Arduino's 5 V signals to the 3.3 V levels used by the Qwiic system.
The four Qwiic connectors are connected to the same I2C bus, allowing multiple sensors and modules to be connected without soldering. Qwiic uses 4-pin JST connectors with 1 mm pitch and a polarized design to prevent incorrect connections. Multiple Qwiic devices can be daisy-chained, provided they use different I2C addresses.
The expansion board also features a large prototyping area with solder pads for custom circuits, groups of three connections, and connections for GND, 5 V and 3.3 V.
Female headers for Arduino R3/R4 are included but are not pre-installed and must be soldered in place before use.
