{"title":"BBC Micro bit Prototype Expansion Board","handle":"bbc-micro-bit-prototype-expansion-board","url":"/products/bbc-micro-bit-prototype-expansion-board","description":"This prototype expansion board breaks out all of the BBC micro:bit's edge connector pins to labelled headers and includes a small breadboard for building circuits. It provides a beginner-friendly way to learn electronics and programming with the micro:bit, making it easy to connect sensors, LEDs, motors, and other components.\n\nThe board supports multiple power supply options: external DC input (VIN or VCC), USB power via the micro:bit, or direct connection to the micro:bit's edge connector.\n\nKey Features\n\n\nFull Pin Breakout – Access to all micro:bit pins (P0–P20)\n\nBuilt-in Breadboard – For prototyping circuits directly on the board\n\nMultiple Power Options – External DC, USB, or micro:bit powered\n\nPower Output Headers – VIN, 5 V, and 3.3 V output connectors\n\n\nSpecifications\n\n\nDimensions – 62 × 82 mm\n\nInput Voltage – 6–24 V (VIN) or 3.6–6 V (VCC)\n\nDigital Pins – P0–P20\n\nAnalogue Pins – P0, P1, P2, P3, P10\n\n\n\nPower Supply Notes:\n\n\nVIN (6–24 V): Use for external supplies above 6 V. Provides power output on VIN, 5 V, and 3.3 V headers.\n\nVCC (3.6–6 V): Use for external supplies below 6 V. No power output on VIN or 3.3 V headers.\n\nUSB via micro:bit: Connect the micro:bit and power via USB. Only the 3.3 V header has power output; VIN and 5 V headers are inactive.\n\n\n\nPackage Contents\n\n1× Prototype expansion board for micro:bit\n1× Breadboard\n","vendor":"Elecrow","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":6952,"title":"Default Title","sku":"EC-DTS04512B","price":21.45,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":108,"option1":"Default Title"}]}
