Product Description

Monk Makes Power for the BBC micro:bit

Please note, BBC micro:bit and batteries are NOT INCLUDED

The MonkMakes Power for micro:bit opens up lots of ways of powering your micro:bit.

This tiny board has a standard DC barrel jack socket at one end and provides a regulated 3.3V output that you can use to power your micro:bit using the JST battery connector attached to wires coming from the other end of the board.


  • Input connector: 2.1mm DC barrel jack connector positive center connector
  • Output connector: JST-2.0mm on flying leads
  • Voltage regulator IC: LD1117-3.3V – datasheet

AC Power

If you need to power your micro:bit project for long periods of time, then you are going to get sick of changing the batteries all the time. By using an AC adapter (not included, but 6V recommended) you can power your micro:bit indefinitely.

Higher BBC micro:bit 3V Output Current

When powered from USB power, your micro:bit can only supply a maximum of 90mA of current through its 3V connector. This means that powering Neopixel LED displays or servomotors that need more current, may not work, or be reliable. The MonkMakes Power for micro:bit boosts this maximum output current to a much more respectable 700mA. Enough to power far more Neopixels (the exact number depends on LED brightness) but // todo – verify max number at full brightness//.

Using Bigger Batteries

The standard AAA battery pack works well, but will only last for a few days of continuous use of the micro:bit. By using the Power for micro:bit with a bigger battery pack with a DC barrel jack (you can achieve much greater battery life). For example, using a 4 x AA battery pack should provide roughly 4 times the battery life that you would expect from a AAA battery pack.

Awesome service with super fast delivery. The chat option really helped me choose the products, know they were in stock and would be delivered in time. The items were posted the same day and I couldn't believe it when they arrived from Perth to Melbourne in 3 days! Thanks for your wonderful support - our students were able to complete their robotic projects in time.
