More!

With this you get more processing, more GPIO, more power options, and more convenience in programming due to its Blu tooth built into. What possible more could you want; Bluno M3 is all you really need!

Requires unsigned drivers, old IDE and Mac/Lunix not supported

I've still not managed to connect to this device due to the fact that it requires installing unsigned drivers. Mac and Linux not supported. I don't recommend getting this microcontroller. I haven't got it to connect, so it's useless to me. If you still really want it, I suggest you try to jump through the installation hoops before spending any money... https://www.dfrobot.com/wiki/index.php/Bluno_M3_SKU:DFR0329 Good luck!
