This ultra-compact Qwiic breakout allows you to use non-Qwiic I2C sensors/devices with your Qwiic-based project. It also allows you to do things the opposite way - breaking out Qwiic devices to simple pads for hooking up to your circuit in whatever way you decide - soldered wires, terminal blocks, headers and more. Another handy way to use this breakout is to solder the included 4-pin header to the board and use it as a breadboard adapter for Qwiic devices - handy! I2C and Qwiic devices use four lines for power and communication - GND, 3.3V, SDA and SCL. The pads on one side of this breakout connect these lines to two Qwiic connectors, and all share the same lines. This allows a few different use cases to help you hook up the parts from your project: Use the breakout to: * Connect a non-Qwiic I2C device to a Qwiic system * Break a Qwiic sensor out to pads * Join two Qwiic cables together using the two Qwiic ports (pads unused) * Connect a Qwiic device AND a non-Qwiic device to a Qwiic host microcontroller (devices will require different I2C addresses) * Connect two Qwiic devices to a breadboard using the included pin header (devices will require different I2C addresses) * ...and more! If you're soldering wires, consider using the underside solder pads. We added these because we know just how tricky it is to de-solder and re-solder a wire from a pad hole. With the underside pads, it's much, much easier to re-work and re-use. We also used M2.5 mounting holes as they're a popular size with easy-to-source fixings...and because we detest fiddly M2 fixings.
