Features: brand new and high quality The Build HAT fits any with a 40-pin GPIO header and lets you control up to four LEGO- Technic motors and sensors from the LEGO- Education SPIKE Portfolio, a flexible system with unlimited possibilities. Onboard RP2040 microcontroller manages low-level control of LEGO- Technic devices. Onboard 4x LPF2 connectors for LEGO- Technic motors and sensors. 40PIN GPIO interface. With external 8V power supply, allows powering your (except 400, cause it can'for t be powered via GPIO) and all connected devices.
