Review on Seeed Studio Seeeduino XIAO Grove Shield Extension Board for Enhanced Battery Management and Bonding Pad by Mike Cassidy

I mainly use Arduino Nano for my projects. I recently had a project that would benefit from a faster processor. I first tried Redboard Artemis but found that with their proprietary connection i2c I/O on this device they screwed up. This XIAO worked great with the code I had already written for my Nano. The small size is good too. They contain a sticker to identify the contacts. I think because the chip cap prevents them from using labels engraved on the PCB. They cost a little more than the Arduino Nano, but I think the increased speed will make the cost worth it.
