Introduction

The Bluno M3 is a new Arduino compatible prototyping platform based on a 32-bit ARM processor. This microcontroller integrates a Bluetooth 4.0 chip and a STM32 ARM controller on the board. As a new member of Bluno family, Bluno M3 comes with some common Bluno features, such as bluetooth connectivity, Bluetooth wireless programming and mobile phone control support. In addition, thanks to its new 32-bit microcontroller, it has more powerful performance, more storage space and more interface resources.

The ARM processor is famous for its efficient processing performance, but one of the downsides to this is that its developing environment is also quite complicated. Bluno M3, a new product designed by DFRobot, changes this. The rewritten underlying protocol and development environment have been rewritten to accommodate for Arduino language usage, giving it full Arduino compatibility. Bluno M3 has 512K flash memory and 64K SRAM, and the integrated Bluetooth 4.0 (BLE) supports Bluetooth wireless control or Bluetooth wireless programming.
 
Note: The special IDE only supports Windows currently.
