Mbits ESP32 Dev Board based on Letscode scratch 3.0, Arduino


The Mbits board is based on the Micro:bit board but with some differences. With Mbits you will have increased RAM memory (from 128KB to 8M) and due to its ESP32 you will be able to connect your board to Wi-Fi. In terms of Software this board can be used with Arduino or Letscode and if you already have an expansion board for your Micro:bit you can use them on this new board as these two are compatible.

Mbits is a pocket-sized microcontroller that has lots of features the same as Microbit V2. Mbits is an ESP32-WROVER-B based educational hardware suitable for kids to learn how to program and experience hot topics such as IoT and AI.

The Mbits board is 52*52mm in size. Continues the style of the edge connector on the bottom of the BBC Micro: bit. If you already own Micro: bit expansion boards. Mbits is compatible with Micro: bit expansion boards, which enabling users to easily start the project with no need for any other knowledge support.

Integrate many inputs and output hardware such as 25 full-color LED lights, microphones, buzzers, enabling you to create a variety of interesting interactional works. If you want to realize wireless projects, it is equipped with a 2.4GHz micro: bit radio and BLE Bluetooth 4.2. It supports two programming software-Letscode(base on scratch 3.0) and Arduino. 

Letscode is graphical programming software created mainly for the global needs of science and technology innovation education. With letscode, you can program by only dragging the building blocks with the mouse. It can help you learn the program of game design and robot control easily.
