Issue with bob2
Ossciliscope don,t work powered from li ion battery(battery has 4.015 volt). From usb it work. V+ =0. One leg of bob2 has battery voltage. When i connect 5v from usb, red light is on and battery changing . It seems that bob2 partically worked. How to make dso working from battery?
Re: Issue with bob2
With USB power removed and battery connected do you get correct voltage at BOB2 pin4? This voltage should be close to battery voltage when the scope is off. If you don't then BOB2 may be fault. You can also try directly connect battery to BOB2 pin4 (bypassing BOB2) to see if the scope can be powered on.
