I have purchased Grove Base Shield printed V2.1 08/31//2015 from Japanese Distributor. I found Connector Silk Printed A0-A3 are wrong and those should be
A1-A4 or circuit board line connection are wrong. I did not confirm, but Dx might have same problem. The Shield also have small problem that right upper side pin connector
is not inline. Is anyone have similar problem ? Is my V2.1 Shield official product ?
