SAMD21 giveaway

What:
I’d like to give away one SAMD21 logger/sensor board to someone, wherever in the world you are.

Why:
I’m a hardware guy, not a programmer. I’ve had fun designing this project and wrote simple code to verifying everything works. There is enough hardware and sketch space available to create a pretty cool logger project. Just let me know at @mikerankin what projects you’ve worked on in the past and what you would like to create with this design. If I like your idea then you can have this prototype. The only catch is that your code written using the Arduino IDE will be posted to my git site to share with others
