{"title":"micro: IoT - micro:bit IoT Expansion Board","handle":"micro-iot-micro-bit-iot-expansion-board","url":"/products/micro-iot-micro-bit-iot-expansion-board","description":"The micro:IoT is a feature-packed IoT expansion board for the BBC micro:bit. It integrates Wi-Fi connectivity, an OLED display, motor drivers, servo outputs, and a range of I/O ports into a compact cloud-shaped PCB — everything needed to build IoT projects with minimal setup.\n\nDesigned to work with the DFRobot Easy IoT platform, the board lowers the barrier to building connected projects. It supports MakeCode, Mind+, and Python programming environments. A PMMA protective case shields the onboard components.\n\nKey Features\n\n\nIntegrated Wi-Fi Module – Connect to IoT platforms wirelessly\n\nOLED Display – Show sensor data and status information on screen\n\n2-Way Motor Driver – Control two DC motors directly\n\n2-Way Servo Output – Drive two servos for robotic projects\n\n6-Way I/O Ports – Standard Gravity-compatible connectors (P0, P1, P2, P8, P12, P16)\n\n3× RGB LEDs – Programmable onboard lighting\n\nOnboard Buzzer – Audio output with switch control\n\n2-Way I2C & 1-Way Serial Port – Additional communication interfaces\n\nLi-Ion Battery Holder – CR123A 3.6V rechargeable battery with onboard charging circuit\n\nSafety Protection – Short-circuit and reverse-connection protection\n\n\nSpecifications\n\n\nPower Supply – Li-ion battery or external power\n\nBattery Type – CR123A 3.6V rechargeable Li-ion\n\nSTM8S I2C Address – 0x01\n\nDigital Output Voltage – 0V / 3.3V\n\nAnalogue Input Voltage – 0–3.3V DC\n\nDimensions – 148 × 112 mm\n\nMounting – M3 screw holes\n\n\n\nWarning: Use only CR123A 3.6V rechargeable Li-ion batteries. Do not use 3V CR123A batteries or non-rechargeable cells. Attempting to recharge non-rechargeable batteries is dangerous.\n\n\nIdeal For\n\nmicro:bit IoT and connected projects\nRobotics with motor and servo control\nClassroom STEM and coding activities\n\n\nResources\n\nProduct Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4753,"title":"Default Title","sku":"DF-MBT0012","price":68.28,"on_sale":false,"in_stock":true,"available_quantity":40,"option1":"Default Title"}]}
