Inside each micro:arcade kit you will find all the components required to build your micro:bit into a full-fledged game system; the only parts not included are two AAA batteries and the micro:bit itself. Simply add your own micro:bit to the provided controller:bit, assemble the kit, and you will be ready to start playing. The SparkFun micro:arcade kit V2.0 is a great way to build the arcade setup you've always wanted! The kit does not require any soldering and is recommended for anyone curious about gaming or the micro:bit platform. When you are ready to control more than just games, the SparkFun controller:bit is equipped with the SparkFun Qwiic system to allow you to expand your curiosity to an ever growing ecosystem of sensors & controllers! Note: The SparkFun micro:arcade kit does NOT include a micro:bit board. The micro:bit board will need to be reserved separately.
