I’ve got a bunch of aging OpenCR 1.0 boards (mounted on TB3) having a faulty power supply. Every time the STATUS LED blinks it slightly drops the intensity of the POWER LED, that’s already a bad sign. Attaching a load, as simple as a Raspberry Pi drops the 5V to 4.5V (the Raspi red POWER LED lights ont but it won’t boot). I think the voltage regulator is dead.
Since several boards of mine act this way, some of you might have expected such issue and made some diagnostics?
