With the development of IoT, there are so many platforms emerging but most of them are mainly designed for the professional user which can be very difficult for beginners to get started with.

DFRobot specifically developed the micro:IoT to overcome this problem - an easy-to-use micro:bit-based IoT expansion board lowering the barrier of entry with IoT.

The micro:IoT board is cute and friendly yet comes with a great feature list - 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 and more! So many resources for you to learn and program!

Without background knowledge and experience, you can build your IoT applications in just a few steps!

DFRobot designed the board as a cloud shape to make it more suitable for the theme of IoT. As for the power supply, the board uses the CR123A 3.6V lithium rechargeable battery (not included). This kind of battery has a small size, high capacity and high safety. What’s more, they added short circuit and reverse connection protection for the product to further improve the safety of using Li-ion batteries.

It's an easy-to-use and efficient IoT teaching tool!
