FOUND Cosam the great bare Neptune genesis 32x board.

Some motivation maybe. This is the one I built from the blank PCB. Those passives are time killers but therapeutic if you're just doing it little by little. Of course I misread one of the values and caused an issue, but eventually found it and put the correct value to fix my problems. The bodge wire you see was 3 weeks of hunting by a group of us. That's why you now see a rev 1.4 and 1.5...lol. Anyways, this was a fun and accomplishing build. Works great.

Is there still SD card access noise on MegaSD when used with the Cosam board? On my VA4 model 2 with 32X it’s very noticeable and distracting.
