I’m using a 9V jack, connected to a power adapter connected to a wall socket.
Yes +9V going into the pcb.
Hard to measure (or to find out where they connect), but I’m getting 3V and 6V, so the voltage divider is working, only it’s getting 3V instead of 4.5V, so the supply is 6V instead of 9V 🙁
Did check R31 (47R), it drops 3 – 3.3V. Hows that possible? Should the led be connected for this circuit to work?
Edit: Removed R34 since I’m using the LED on the 3PDT board. Didn’t solve anything though, still 3 – 3.3V drop over R31.
