Introduction

The Bluno M3 is a new Arduino compatible prototyping platform based on a 32-bit ARM processor. This arduino microcontroller integrates a Bluetooth 4.0 chip and a STM32 ARM controller on the board. As a member of Bluno family, Bluno M3 inherits most common Bluno features, such as bluetooth connectivity, Bluetooth wireless programming and mobile phone controlling. In addition, thanks to its new 32-bit microcontroller, Bluno M3 has a much more powerful performance, more storage space and more interface resources. You may also check Bluetooth microcontrollor selection guide to get more information.

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. So DFRobot has been trying very hard to solve this: the 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 for M3 only supports Windows currently.
