As per the Femto standard, knocked it out of the park with a hell of a design. There's no way so much power and connectivity should fit in the size of a thumbnail, yet here we are. Can't wait to see what comes next!
I just try to upload a IMU demo program following the tutorial, however the FemtoBeacon coin, a FemtoBeacon RF dongle is not working! and I request a replacement, but there no information to contact the company

Really amazed at all the capabilities in such a tiny, reasonably priced board. I am attempting to use the board as a USB host for midi instruments, and there were very few options of boards that had host capabilities. I do wish there were more examples for the specific areas I'm focused on, but the maker has been very helpful. I recommend you give it a whirl, I think you'll be impressed.
This wunderfull super tiny board can be easily used with Arduino, after installing the official Arduino SAMD21 library. It really amazed me what this tiny little thing can do! And it's fully compatible with all my older Arduino projects, no hassle with porting from AVR to ARM. Don't really know what to say, other than buy this tiny wonder of technology - for this price and quality, it's more than worth it :)
I picked up one of these so I could build my own Arduino-based circuit board to power my paintball gun and write my own code for it. The Femtoduino is the only Arduino board small enough to work. I built some breakout boards to connect to it and test with. All works well.
It was a little tricky doing the soldering since the holes are so tiny, but I managed to get it done without any issues.
Having on board USB and not having to setup my Uno board for ICSP is great.
I do my initial testing on a breadboard setup with a Nano board on it. All I need to do to use the Femto is swap USB cables, change the Board/Serial port and upload. It's nice and easy!
I would, however, like to see the Femtoduino Shield sold as a separate product, though. Or maybe make a store item that has both the USB version and Shield.
