GroveHat for the Arduino Nano

I really wanted to make this board because I felt it was useful not just for me, but useful in general. The initial production run was 30 boards, using Seeed Studio's FusionPCB service. Now that's almost all gone. It's time to do a bug-fix update to the Gerbers and do another production run! Things likely to change:

• Pinout to make I2C compatible with all 3 relevant Arduino boards
• Silkscreen fixes

Have any other feedback to me? Would love to hear, please let me know!

Also, if you are affiliated with a hackerspace, drop me a line and I'd be happy to send you one board to try!
