micro: IoT - micro:bit IoT Expansion Board

Description

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. It's an easy-to-use and efficient IoT teaching tool, using this product, you can learn lessons related to IoT, such as: On-board 3-way RGB LED On-board buzzer and Switch
