PaulS:
Power is 9V battery.
Which is next to useless.
You should not be putting 9V to Vin.
Why i cant putt 9V battery to Vin? In manual said that: any voltage between 6 and 20 volts as Vin will work. 7 to 12 volts is highly recommended!!!
- I will check and see the magic or not
- No Gnd are separate
Because i need two devices.
