MI:power powers the BBC micro:bit via a 3V coin cell battery and is intended to make it easier for the BBC micro:bit to be used within wearable tech projects, such as designing a smart watch of pedometer.
The Nottingham-based educational technology specialists write:
The stylish, lightweight PCB is designed to fit snugly against the BBC micro:bit and features a built in piezo buzzer, 3V coin cell holder and easy access on/off switch which means that the device does not have to be disconnected from the power supply in order to switch off a project, as is currently the case.
The MI:power board is priced at £4.14 excluding VAT and £4.98 including VAT. It includes:
- 1 x MI:power board for the BBC micro:bit
- 3 x Counter Sunk M3 x12mm Machine Screws
- 3 x M3 Hex Full Width Nuts
- 3 x Plastic Spacers
- 1 x CR2032 3V Coin Cell.
Note that a BBC micro:bit is not included. Full details can be seen in this PDF.
The BBC micro:bit, a 4cm by 5cm device, is powered via a USB cable, or otherwise via a battery-pack accessory.
“The potential for the BBC micro:bit to be used within wearable tech projects is huge,” said Kitronik co-founder and director Geoff Hampson. “We believe that being able to create their own wearable tech is something that will hugely interest children who are now getting to grips and experimenting with the BBC micro:bit.”“However, we found its wearable potential was being somewhat limited due to its power source which is why we have created MI:power which enables the device to be powered via a 3V coin cell battery. The portable nature of the BBC micro:bit demands that its power source be just as portable and we feel that the MI:power device addresses this.”
