Safety Advice

Safety first!

Using the BBC micro:bit is fun and simple but like with any electronic device, a little bit of care and caution will ensure you and your micro:bit will stay fit and healthy.

Please read these instructions carefully!

To start with... Naturally, the BBC micro:bit is designed to be safe to use. However, unlike electronics you might buy in a shop, there's no protective case - all the electronics are exposed. We designed it this way so you can see how the electronics are assembled. It looks neat, but needs to be handled with care. With the electronics accessible like this, it's important to avoid generating static electricity. You can discharge any static you've built up by touching a metal object to 'earth' yourself. A chair or table leg would be a good choice. No need to cling on to it for dear life - just a quick touch is all you need.

Once you're sure you're static-free, you can start handling your micro:bit and get it plugged-in! Examine the board for any damage and monitor it when it is first switched on. Your micro:bit is designed to run cold, if it becomes hot to the touch please stop using it and report this fault to If your micro:bit was purchased, please contact the supplier for how to return your micro:bit.

We think it's a really sound idea that all BBC micro:bits are first connected and used in the classroom, where a teacher can supervise; or with a parent if you're at home. In case you get stuck, there's plenty of great getting started advice right on this site! Check out our Getting Started page for more information and instructional videos.

Our Four Top Tips

In addition, there are four key safety points we’d like to draw your attention to:

  • Always keep your BBC micro:bit in the anti-static bag when not using it. It's good practice for students to earth themselves before handling it.
  • Only handle the BBC micro:bit by its edges and avoid touching the components when the power is running.
  • Please use the battery pack and the USB lead provided to power your micro:bit. Do not use portable battery chargers or USB charging ports (often marked with a lightning bolt or 'SS'), to power your micro:bit. Using these may damage your micro:bit and stop it working properly.
  • Please don't let your pupils keep damaged BBC micro:bits. If you find any faults or damage to a micro:bit, contact immediately and replace the device with one of the spare micro:bits we've supplied.
