Board is 100*150mm, no problem for Eurorack.
Thanks! 'ELO is pretty much ready to go, I just need to confer with Peter whether that's a good enough start for Programma or if he wants to work on the concept a bit more. If you're interested in PCBs and your own development I can send you some. The display driver is fine -- with one small bug that I mirrored the J15A connector. Not in the board file this time, but months before in the schematic... It needs a workaround by either attaching the header pins to the bottom of the PCB or twisting pairs on the ribbon cable (only the first 6 wires of J15A).
Best,
