Out of stock

BitMaker is a credit card sized extension board designed for connecting micro:bit with convenient plug and play Grove modules. The Grove series has different kinds of sensors, actuators, communication modules and displays etc which will extend the micro:bit's allowing students to create more exciting projects.

The BitMaker also integrates a buzzer and 4 neopixel RGB LEDs. The touchable pins P0, P1 and P2 are also reserved for connecting banana plugs or crocodile clips if you are a fan of making a fruit piano.

BitMaker is an expansion board for micro:bit.

It is designed for micro:bit users to discover cool and amazing functions of micro:bit. It's very easy to use - you just have to slide it into the micro:bit and then connect your chosen Grove module to a connection port. If you haven't heard of Grove before, Grove is a Seeed series which you can read more about here. BitMaker has inbuilt programmable RGB LED and a buzzer to allow beginners to extend their micro:bit projects even before they add additional modules. 

The touchable pins P0, P1 and P2 are also reserved for connecting banana plugs or crocodile clips if you are a fan of making a fruit piano.


If you wish to start out adding Grove modules, we recommend that you buy a BitGadget Kit which includes a BitMaker and 9 different Grove modules! This is a nice choice for micro:bit intermediate learners to carry out their micro:bit experiments.

  • Education Focus

With the BitMaker, students will develop open source electronics understanding as well as programming skills. Students must exercise creative thinking and use their hands as they design their own projects, customising functions through graphical programming. Not only can kids build knowledge of the modules and graphical programming, but they can also learn how to create their own DIY projects.
