Good morning,
finally I have assembled everything: raspberry pi 4, hat2, MCS with openplotter2.
All up-to-date and working. Lastly I installed a 240 gb external non self-powered SSD connected to usb3 with openplotter and eliminated the sd card. But due to the voltage drop that OP detects .... I plugged in a self-powered HUB and consequently attached the SSD to the HUB. I got the power supply from the GND pin and from the +12 enable pin so that when the system is turned on, the HUB is also powered. BUT here's the problem: at shutdown that MCS should do it doesn't happen until I turn off the power to the HUB.
Solution????
Thank you
