This Relay Breakout Board for BBC micro:bit is a versatile accessory that enables the micro:bit to control higher-voltage devices, such as home appliances, through four onboard relays. It's particularly useful for projects involving automation, robotics, and smart home systems.

Key Features

• 4-Channel Relay Module: Equipped with four 5V relays, each capable of switching up to 120V AC at 3A or 24V DC at 3A.
• Active HIGH Control: Relays are activated with a HIGH signal, simplifying control logic.
• Dedicated Micro:bit Pins: Each relay is controlled via micro:bit pins P3, P4, P6, and P7.
• Integrated Voltage Regulators: Includes onboard 3.3V and 5V regulators to power the micro:bit and connected peripherals.
• Simple Setup: Insert the micro:bit into the breakout board and supply 5V DC to the VIN/GND terminals to operate.
