If one looks at the diagram at https://wiki.seeedstudio.com/Wio-Terminal-IO-Overview/, the faint layer in gray shows that the buttons are nearest the bottom-left corner of the image, with the header (also) left of center. For this to be the case, this must be a TOP see-through view of the product.
This is inconsistent with the rest of the graphic which also suggests that the windowed side of the product is facing the user, which shouldn’t be true if this were the TOP view because you’d expect to see the blue button instead.
HOWEVER, a check of the pins with the voltmeter on the 5V/3V3/GND pins that are at one side of the header proves that the image is INCORRECT. For the layout orientation of the header to be correct, it must be the case that this image is meant to depict the BOTTOM view of the product, instead.
The layout graphic needs to have the three buttons moved from the bottom-left quadrant of the image to the top-left quadrant of the image. This would then make it the correct view of the case plastics and the header to match the rest of the artwork for this diagram.
My other strong suggestion would be to EXPLICITLY state in the image graphic that this diagram is “Bottom View”. This would save users a lot of time trying to figure this out (or guess) themselves, rather than trying to squint and discern all of the other details that are in light gray like the plastic recesses and the faint blue buttons which are barely visible below the foreground graphics’ pin name labels.
I’m really, really glad that I double-checked this because my PCB to connect to this header would have been scrap.
