I noticed on my IC5 (ordered using the English support Mouser project) the silk screen on the board is reversed. When I assembled mine & did the voltage check before attaching the Seeeduino Mega board I noticed the 3.3 VDC was at about 4.5 VDC. in looking at things I found IC5 was installed backwards even though it matched the silk screen on the board. I removed it and installed it in the correct orientation & I had the proper 3.3 VDC.
