Building Block Expansion Board with Cable for UNIHIKER M10 (Wireless & LEGO-Ready)

The Building Block Expansion Board Bundle for UNIHIKER M10 is the dedicated expansion solution designed specifically for the UNIHIKER M10 single-board computer. Unlike the UNIHIKER K10 or micro:bit which connect directly, the UNIHIKER M10 requires this specific custom cable to bridge communication with the expansion board. This connection unlocks the full potential of the UNIHIKER M10, enabling it to drive motors, servos, and sensors while mounted on LEGO structures.

Note: If you are using micro:bit or UNIHIKER K10, you do not need this cable. You can purchase the standalone board.

Cable-Free Mobility

A robot is not truly "mobile" if tethered to a wall outlet. This board addresses this limitation with an integrated rechargeable 18650 battery holder. It powers the UNIHIKER M10, motors, and sensors simultaneously via the battery, eliminating the need for external power banks. Additionally, the support for solar charging enables the creation of fully autonomous outdoor projects.

Seamless LEGO Integration

The design eliminates the need for adhesives or tape to attach electronics. The bottom of the board features a standard LEGO-compatible base, allowing it to snap securely onto beams and plates. This structural integration transforms the electronic module into a seamless part of the mechanical build.

Optimized for UNIHIKER M10 & Cross-Compatible

While the expansion bundle is tailored for the UNIHIKER M10 (via the included cable), the board itself remains fully compatible with micro:bit and UNIHIKER K10 (via direct plug-in). This makes it a versatile asset for classrooms or workshops that utilize multiple generations of educational controllers.
