The MI:power board for the BBC micro:bit brings real portability to your wearable projects. The stylish, lightweight PCB is designed to fit snugly against the BBC micro:bit and features a built in buzzer and 3V coin cell holder.

When assembled, the MI:power board is connected directly to the 3V, GND and P0 connections on the micro:bit. The 3V and GND connections provide power to the micro:bit and the built in buzzer is connected to P0, which is the default output pin when using the audio functions in the Block Editor software.

The board has an easy to access on/off switch, which makes it easy to turn a project on and off, rather than have to disconnect the power supply from the BBC micro:bit.

Once the unit is assembled and attached to the BBC micro:bit the mechanical fixings prevent the battery from being removed unless you use a screwdriver, so whatever the use, the battery will remain safely in place.

Spacers, fixings and a battery are all provided.

Please Note: BBC micro:bit is NOT included.

Features:

  • Power your BBC micro:bit from a stylish PCB.
  • On-Board buzzer.
  • Easy access on/off switch.

  1. Great for making the micro:bit mobile Review by Lorrainbow
    Rating

    This is a nice little battery kit that makes the micro:bit very mobile and compact. My only problem is you can't replace the battery without disassembling it. It would be nice if you could pop the old battery out and a new one in without unscrewing the bolts. (Posted on 22/07/2017)

    A: Hi Matt, I have just taken a look at one on the shelf, the plastic spacers do seem a little tight however they do go on and it is likely down to tolerance that is making them a little snug. I used a screw driver and a pair of pliers to hold the plastic spacer, I was then able to screw the board together in a few moments. Hope this helps.

    Hi Holger, With regards to the issue you are experiencing I can confirm that having the MI:power board attached won’t be the cause of this. There is a diode both on the MI:power board and on the micro:bit which ensure that power is only drawn from one source at a time. It will draw power from which ever source has the highest voltage. As such the issues you are experiencing are related to the micro:bit units themselves and it is possible you have received a damage unit(s). As such it would be best to contact the supplier you received these from, if it was ourselves please contact support@kitronik.co.uk.

    Hi John, the easiest way to test this is to upload some simple code that turns P0 on and get this to output a frequency between 200Hz to 10kHz, this should then make the buzzer sound. You also need to ensure the battery is correctly inserted and that the screws are making contact with the micro:bit.

    Hello, I’m very surprised to hear the switch on the board is easily broken. As the tab is small it should be difficult to snap off by hand. As the switch is a small surface mount component it isn’t possible to get a replacement, it would need a replacement complete board.

    Hi Graham, it shouldn’t break anything if the power is left turn on with the MI:power board and it is plugged into the USB port, it would be similar to if the battery cage was left plugged in when it was plugged into the PC. However it is recommended that only one device is used to power the micro:bit at any one time.

    Hi Dan, There currently isn’t anyway to monitor the remaining charge in the coin cell battery. The easiest way would be to measure the voltage on the 3V pin on the MI:power board, using a multimeter. You may also notice the LED’s on the BBC micro:bit getting slightly dimmer.

    Hi Mark, Unfortunately there isn’t any voltage protection built into the BBC micro:bit or the MI:power board, however there is a diode on the MI:power board which would lower the voltage slightly (0.1-0.2V). We however can’t guarantee that this would protect the BBC micro:bit as the power supply should be 3V’s.

    Hi Jake, We are in the final stage of developing the case and getting it ready for stock. We currently estimate that this will be available to purchase by the end of august, signing up to our newsletter will likely make sure you are aware as they should be included in there once they are live.

    Hi Dan, setting the pin high won’t do anything, as sound is a vibration so you would need to swap the pin from high to low very quickly. Using the music function is the easiest way to do this.

    Hi Edward, The MI:power board with the screws and battery weights approximately 16g. You may be able to use a super capacitor, however this isn’t something we have tried and as such the results are unknown for this.

    Hi Hugh, there shouldn’t be an issue, it would be a similar situation if you were using a battery cage to power the BBC micro:bit and left that plugged in while connecting to a PC. However it would be advisable to always turn the MI:power board off before connecting to the USB port.

    If the BBC micro:bit was connected to the power board and was just used to scroll text across the LED mounted on the board it would last between 10-20 hours. Once you connect items to the outputs this would alter.

    A: Hi Peter, Unfortunately that part is a buzzer that we surface mount with our in house machinery so is not suitable for general purpose, as you would need a pick and place machine. Best Regards Cullen
