You have a BBC micro:bit, but perhaps a compact embedded computer is just sitting around gathering dust. It’s time to clean it up and use it again!
A wide range of accessories has been released for this device, allowing you to expand the functionality in a way that you could never have dreamed of.
Here are some of the best micro:bit add-ons that allow you to do something new with your device. Please note that none of these kits come with the micro:bit itself, which is available separately.
1. Electronic starter kit
If your BBC micro:bit is gathering dust for lack of compatible (or easily pluggable) components, then this electronic starter kit from Monk Makes is a great option.
This kit, including speaker, relay, touchpad, fan motor, light bulb, 10 alligator leads, one AA battery, and 30 page manual, is perfect for a number of great projects.
The guide includes several projects, with a block editor and MicroPython options. Among the projects you will find a motion alarm, a «shout meter», several ways to manipulate a fan, and a magical tool similar to theramine.
2. Protective silicone case for wearable
One of the most popular ways to use the BBC micro:bit is as a wearable device that uses an LED matrix to display text or an image. But attaching the device to clothing can be a bit tricky. While you might like the idea of making a handmade cotton pouch, this protective silicone case is a much better solution.
Designed to provide full access to pins, A and B buttons, USB ports and other connectors, these cat microplates come in blue, yellow, red or yellow.
3. Ring: bit expansion board
Looking for a way to connect your micro:bit to servos with a built-in battery box? Something perfect for, say, building a micro:bit car? The answer is the Ring:Bit expansion board, which comes with a function select switch, a power switch, and two sets of pins. This board supports up to three servos and has room for three AA batteries.
4. Inventive kit
Once you have done everything in the starter set, the only way is up. The Micro:bit Inventor kit from Kitronic features a connector board designed for use with breadboards, one of which is included in the kit. There is also a collection of LEDs, LDRs, capacitors, fan, motor, switches, wires and a tutorial.
