Hello,
I'd like to test that my UTCOMP PRO and OLED display are functional prior to installation. What is the bare minimum of connections required to test OLED and configure UTCOMP-PRO with a computer? When preconfiguring with PC, is a power source needed or does it draw power from the USB? If I need to supply power, do you see any issue with running off my PC power supply +12VDC rail?
