Hi all, I am just swriting to let you know I solved the issue. I happened to not knpw the most important voltage on the D32 was 5 volts. I solved the issue just using a 5 volt PSU (indeed, a USB PD capable one, providing up to 5 V/2.24 A) and getting both 12 V and -5 V out of it. Everything is worki...

Further info: I am feeding the system with 9 volts at 2.22A, converted to 12 volts and -5 volts, and from 12 volts to 5 volts. I am doing it this way because when I was converting directly from 9 to 5, the power loss was noticeable (the 5 volts path was falling up to 3 volts). I have to test with a ...

Hi everyone, first of al, thanks to admit me to join this awesome community. Two months ago I purchased a Dragon 32, and I was able to test two days ago. The unit lacks the PSU, so I bypassed the power board and directly fed 12, 5, -5 and GND to the first four pins of the connection between power an...
