These cables are custom-created for the MakerBit and MakerBit+R to supply BOTH power (5v from the USB connection) and a serial data connection.

The micro:bit AA battery case only provides 3volts, which is not enough for accessories like the Audio Narration playback module (mp3), ultrasonic range sensor (for smart cars), and certain other add-ons.

Even with a USB connection to the micro:bit, the micro:bit is very limited on the amount of power that it can handle (about 90 milliamps).

With this special cable, the micro:bit gets the serial connection it needs, and your project gets the power that it needs (1000 milliamps or more).
