{"title":"1 Channel Relay 3V Relay Module for Micro:bit","handle":"1-channel-relay-3v-relay-module-for-micro-bit","url":"/products/1-channel-relay-3v-relay-module-for-micro-bit","description":"A single-channel 3 V relay module from the ElecFreaks OCTOPUS series, designed for use with the BBC micro:bit. It uses a high-quality HUIKE relay capable of switching loads up to 30 A, making it suitable for controlling home appliances and other high-current devices.\n\nThe module runs on 3 V power, which the micro:bit can supply directly. It connects via a standard OCTOPUS electric brick connector and includes both normally open (NO) and normally closed (NC) contacts.\n\nKey Features\n\n\nChannels – 1\n\nOperating Voltage – 3 V (micro:bit compatible)\n\nMax Switching Current – 30 A\n\nContact Type – Normally open (NO) and normally closed (NC)\n\nConnector – OCTOPUS electric brick connector\n\nSeries – ElecFreaks OCTOPUS\n\n\nGetting Started\n\nConnect the relay module to P1 on an octopus:bit breakout board using a jumper cable\nInsert the micro:bit into the edge slot of the octopus:bit\nSet P1 to high to close the normally open contact (and open the normally closed contact)\n\n\nIdeal For\n\nBBC micro:bit projects requiring relay switching\nControlling lights, motors, and other high-current loads\nEducational electronics and home automation experiments\n\n\nPackage Contents\n\n1× Single-channel 3 V relay module\n\n\n\nWarning: This module can switch high-current circuits. Ensure all high-voltage wiring is performed by a qualified electrician and meets local electrical safety regulations.\n\n\nResources\n\nMakeCode Example Program\n","vendor":"ElecFreaks","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3969,"title":"Default Title","sku":"EF-EF04086","price":9.48,"on_sale":false,"in_stock":true,"available_quantity":107,"option1":"Default Title"}]}
