Seeed Arch Max is missing 5V voltage on Arduino header - fixed

The Seeed Arch Max is missing 5V voltage on Arduino header. I have fixed this by running a thin wire from the 5V test pad on the back side of the board to the 5V Arduino pin. I have two of these boards, both needed this patch wire. /media/uploads/JackB/20150514_102720r.jpg

Looking at the schematic it looks to be a unconnected net, where the test point name matches but does not connect to the net.

I'm kind of lean toward them having a vision that VIN came in on a different shield, along with a 5V regulator.

I too have a couple of these boards, but think Seeed dropped the ball from a couple of perspectives, mainly the shield header wiring for USARTs, J4 is arguably backward, the extra USART's aren't handled in a Arduino Mega fashion, and the MicroSD card uses SPI rather than SDIO.

For similar boards see GHI's FEZ Cerbuino/Bee, Lemur and Panda III boards, and new Nucleo-144 series.
