It provides four ports for LEGO LPF2 (Powered Up) components, allowing direct control of motors, sensors, and lights from your Pi. Ideal for robotics projects, prototyping, and educational builds.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e7.5–9V DC (via barrel jack or terminal block)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLEGO Ports\u003c\/td\u003e\n\u003ctd\u003e4x LPF2 connectors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor Support\u003c\/td\u003e\n\u003ctd\u003eLEGO Technic motors (medium, large, etc.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor Support\u003c\/td\u003e\n\u003ctd\u003eLEGO color, distance, and force sensors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication\u003c\/td\u003e\n\u003ctd\u003eUART via GPIO (serial)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBoard Dimensions\u003c\/td\u003e\n\u003ctd\u003e56.5 × 65.0 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eA LEGO rover with autonomous navigation using Pi-based code\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/arduino-color-sorting-kit-tcs3200-servo-machine-for-kids\"\u003eAn interactive sorting machine using color and distance sensors\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-gesture-controlled-robot\"\u003eA Raspberry Pi turtle robot with gesture controls\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eAn educational kit for teaching Python and robotics to students\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThis HAT is compatible with all Raspberry Pi models featuring a 40-pin GPIO header, including the Pi 4, Pi 3, and Pi Zero 2 W. It works exclusively with LEGO LPF2 components; older NXT\/EV3 parts are not supported. Pair it with any Raspbian-based OS and the official Build HAT Python library.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eSecure the HAT onto the GPIO header with standoffs to prevent shorts. The board requires an external 7.5–9V DC power supply (not USB) – connect via the barrel jack or screw terminals. Ensure the power plug tip is center-positive. No pull-up resistors are needed for LPF2 ports.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery 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.\u003c\/p\u003e\u003cdetails\u003e\u003csummary\u003eIs this compatible with Raspberry Pi 4?\u003c\/summary\u003e\u003cp\u003eYes, the Build HAT fully works with Raspberry Pi 4 and any 40-pin model. Just ensure sufficient power for both Pi and connected components.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eDo I need an external power supply?\u003c\/summary\u003e\u003cp\u003eYes, operation requires a 7.5–9V DC power brick (center-positive). USB power from the Pi is insufficient for driving motors.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eCan I control standard DC motors with this HAT?\u003c\/summary\u003e\u003cp\u003eNo, it only drives LEGO LPF2 motors and sensors. For generic DC motors, consider a different motor driver HAT.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
