3.3V and 5V power interface Accessory Type: Extension Board Compatible With: Micro:bit 5V 1A power supply for greater driving force Benefits and features Provides both 3.3V and 5V power interfaces to expand your Micro:bit projects with highercurrent peripherals. Uses a 5V 1A power supply to deliver stronger drive capability for connected devices, helping motors, sensors, and modules perform reliably. Keeps current loads separated from the Micro:bit, reducing risk to the microcontroller while enabling more ambitious applications. Simple extension board solution that integrates with Micro:bit projects to add power versatility without complex wiring. Practical use scenarios Robotics projects: connect small DC motors or micro servos to a Micro:bit project, using the 5V supply to provide sufficient current while the Micro:bit handles control signals. Peripherals and displays: power highercurrent peripherals such as LED matrices, power LEDs, or sensors that require more current than the Micro:bit can supply directly. Prototyping current modules: run external modules (motors, actuators, or drivers) from a dedicated 5V supply to preserve Micro:bit performance and stability.
