CV_DIP Dumper spacing issue

[jwestfall69]

I have a MVS 161in1 that has the 1.27mm dip style daughter boards for the C and V flash chips. There seems to be a spacing issue with the distance between the 2 double rows of 1.27mm holes on the CV_DIP dumper board.

The below pictures are comparing the double row spacing between the 161in1 board and the CV_DIP dumper board. I'm using 2 pieces of wire to align the left side double rows between the boards. However you can see the right side double row of the CV_DIP dumper are offset to the right by about 1/2 a hole compared to the 161in1's holes.

This extra distance between the left/right double rows of the CV_DIP is enough to make it impossible to insert the daughter board.

If you end up making a new version of the board, please consider adding a stencil outline on the pcb that displays the orientation of the daughter board when installed into the dumper board. I think most people are going to assume the flash chip should be facing away from the STM board instead of it being under the STM board.

Yes, the holes turned out to be slightly off, but I use a header like this and the holes coincide more or less. In the next version of the PCB, if there is one, I will take this point into account and also rotate the flash chip pcb.

Thanks, I got the daughter boards inserted by adjusting my headers to be angled inward a bit like yours.
