Compatibility
This board works with any platform that supports micro:bit, including MakeCode (block-based and JavaScript) and MicroPython. It can interface with 3.3V-compatible sensors, motors, and modules via the edge connector. The micro:bit v2 is compatible with all standard micro:bit accessories and add-on boards such as the Kitronik Inventor's Kit.
Wiring Notes
Power the board via the microUSB port (5V) or a 3V battery pack. Use the edge connector's 3V and GND pins for external components. The pins operate at 3.3V logic; do not exceed 3.3V on I/O lines. For analog input, use pins 0, 1, or 2 with a reference of 3.3V.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
The micro:bit v2 is not directly compatible with Arduino; it uses a different architecture and programming environment. However, you can use micro:bit with Arduino IDE via third-party libraries, but it's not officially supported.
Can I power it with a 5V supply?
The board is designed to be powered via microUSB (5V) or a 3V battery pack. Applying 5V directly to the edge connector 3V pin can damage the board. Use the onboard regulator for 5V USB input only.
Does it include a battery?
No, the micro:bit v2 does not come with a battery. It requires a separate battery pack (3V or 2xAAA) or can be powered via USB.
