This Arduino compatible 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.\u003cbr\u003e\n\u003cbr\u003e\nThe 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.\u003cbr\u003e\n \u003cbr\u003e\n\u003cspan style=\"color:#FF8C00;\"\u003e\u003cspan style=\"line-height: 20.8px;\"\u003e\u003cstrong\u003eNote: The special IDE for M3 only supports Windows currently.\u003c\/strong\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cbr\u003e\n \n\u003cdiv style=\"text-align:center\"\u003e\n \n\u003cdiv style=\"text-align:center\"\u003e\n\u003cem\u003eI\/O Expansion Shield for Bluno M3 \u003c\/em\u003e\n\u003c\/div\u003e\n\u003cbr\u003e\n\u003cbr\u003e\n\u003cbr\u003e\u003cp\u003e\u003cb\u003e\nProject 1: Make Your Own Weather Station\u003cbr\u003e\u003c\/b\u003eThis durable weather station kit includes an anemometer, wind vane, rain bucket and DH11 temperature and humidity sensor.
