I just finished my new test station. It was mostly built to test displays, both eyespi and old. It uses a left over proffie v3.9 test board from oshpark (therefore it only supports v3.9 boards). I designed the lower board for the minimal pins I wanted, and had it fabbed by oshpark. I still had leftover spring pins from the original test boards.
It has 2 buttons, speaker and a kill switch with separate header for non switched installs (pull battery to kill). The pixels seen are connected to data1 and led2.
In addition to the display pin headers, I have easy access to all data, led, and free pads. If needed, I could add connections to the upper test board to get the rest of the connections.
Everything continuity tested good, but I still need to test it out.
For the pins you listed, yes, I suppose. But the oled uses scl, sda which moved. The color display uses free and the data pins are in different places.
I suppose it would workish, but would take too much mental gymnastics (imo) to use it safely.
For testing an OLED, yes I agree. But for testing a v2.2 without OLED, then it is just a matter of changing data1, just to test that the board is working. If you needed.
