Card-sized microcontroller for beginners

The Seeed Studio Micro:Bit V2.2 is a 4 x 5cm board built for children and newcomers learning to program. It supports C++, MakeCode, Python and Scratch so users can create games, animations and simple robotics projects without prior experience.

25 individually programmable red LEDs

The 25 onboard LEDs are the primary visual output and each one can be addressed separately in code. This lets learners display scrolling text, graphics or game sprites directly on the board without any external display.

Low-power classroom operation

The board runs from a small battery pack or USB power and draws only a modest current during typical coding activities. The integrated MEMS microphone and speaker operate at low volume, keeping noise minimal in a classroom or home setting.
