DFRobot micro: IoT - micro:bit expansion board

With the development of IoT, there are so many mature IoT platforms emerging in both domestic and overseas market, but most of them are mainly designed for the professional, which could be very hard for the non-experts to get started. Therefore, we specifically developed this micro: IoT, a micro:bit-based IoT expansion board. Use the board together with DFRobot Easy IoT platform, lower the barrier of using IoT. This micro: IoT board is pretty cute and delicate, on which we integrated Wi-Fi, OLED, 2-way motor drive, 6-way IO port, 2-way IIC, 1-way serial port, 1-way buzzer, 3-way RGB, 2-way servo, Li-ion battery holder, charging circuit, emergency power interface, etc. So many resources for you to program! Even without complicated background knowledge, you can build your IoT applications in few steps! We designed the board as a cloud shape to make it more suitable for the theme of IoT. As for power supply, we selected CR123A 3.6V lithium rechargeable battery. This kind of battery features small size, high capacity, and high safety. What’s more, we add short circuit and reverse connection protection for the product to further improve the safety in using Li-ion Battery.
