Product Description: SparkFun Qwiic micro:bit Breakout - Contact board adapter for BBC micro:bit - with connectors - SparkFun BOB-16446
The micro:bit development boards themselves provide a wide range of possibilities for use in potential projects, offering built-in sensors, accelerometer, Bluetooth and more. For more advanced users looking to expand these basic capabilities, this SparkFun-produced adapter, which allows micro:bit modules to be connected to a contact board, is ideal. SparkFun Qwiic micro:bit Breakout in combination with BBC micro:bit expands the programming possibilities. The board provides access to more pins and allows connection to I2C and SPI buses. This version of the adapter comes with ready made connectors, so you don't have to worry about soldering anymore.
The micro:bit module itself has 3 I/O pins. Using the adapter you have access to all 21 pins as well as to ground and power pins on goldpin connectors (2,54 mm raster) which are compatible with contact boards.

Qwiic connection system
The sensor uses a convenient connection system Qwiicso there is no soldering required to connect it to the rest of the system. The SparkFun Qwiic Connect System is an ecosystem of sensors, actuators, shields, and I2C cables that make prototyping faster and less error-prone. All Qwiic-enabled peripherals use a common 4-pin JST connector with 1 mm spacing. This reduces the amount of PCB space required and avoids connection errors.
