  • Nevermind, I figured it out.

  • Hi, I’m a novice in electronics. I’ve supplied 3.3V to IN1 and 5.0V to HV. GND and HVG are common and I read 4.4V at OUT1 and 0V at OUT2.
    I know I’m not wiring this correctly (when I remove the 3.3V, the 4.4V remains….) The schematic is unclear to me, can someone please help?

No public wish lists :(
