I had a spare linear regulator on hand and now get 3.2v on VCC.
I don’t have a spare zener diode on hand but I can order from digikey. Is it possible to get it working without the zener diode still powering by usb? Obviously it won’t have 24vac to activate a solenoid…but maybe enough to get the ic’s/ethernet working?
During the build initially I tested vin and vcc with the correct voltages before adding the remainder of ics and lcd. After adding those the linear regulator and zener diode became damaged. Do you think there are any other spare components I should get from digikey?
