Yes V-GND and Powersupply GROUND are the same.
Scope GND is not connected. Did not know where to connect it. I have not used a scope much so my understanding of one is low.
1.05V channel output with 100ohm voltage divider.
If i use a resistance of 155 ohms to gnd. I get an output of 1.71 Volts and when output toggle off, voltage reads 74.1 mV.
