So this board didn’t work out properly. Let this be a lesson to double check things…
Easy EDA, the tool I use for PCB schematics and layout, has a vast user-contributed library of parts. But that doesn’t mean they’re accurate. The first board came back with completely the wrong footprint for the resistor array I purchased.
Also, I didn’t realize that the DIN rail mount I bought was vertically oriented until it arrived, so that would have meant the board would be rotated 90 degrees. Functionally no difference, but would have driven me nuts.
So, new board is here, with the proper resistor array footprint, and a new vertical orientation.
