SparkFun moto:bit - micro:bit Carrier Board (Qwiic)

Affiliate disclosure: Everything About Robotics may earn a commission from qualifying purchases through this link. SparkFun handles checkout, fulfillment and returns.

The moto:bit carrier lets a separate micro:bit control a robotics chassis and connect to additional circuits. Its edge connector makes the controller removable, while the onboard H-bridge supports two motors. Servo connections and Qwiic expansion provide room for a project to grow. This board is a component for a planned build, so match it with suitable motors, mechanical hardware and power. SparkFun corrects an older silkscreen voltage marking on the product page: the actual input range is 3–11 V, and the power jack must not receive more than 11 V.
