There appears to be a low-side MOSFET to disconnect the (-) output, with the current-shunt in series on the (drain) low side.
I think this is for "battery charging" or overshoot prevention.

Hi,

someone else has this strange behaviour with bluetooth connection and voltage scan 0-1V 0.1V 1 sec?

It seems the next step couldn't hold each time. Very disturbing.  |O

This happens each scan. Independent of start, end voltage, steps and time.  :-//

I have ordered this module some time ago. I intent to use a micro with two individual rotary encoders, in order to set voltage and current values quickly (through the serial interface).

Alexander.

It works but the module with firmware version 1.3 is really slow with serial commands. Typically it needs more than 400 msec to reply to a command.

As I said... My circuit works, but not what I had in my mind. It also detects CC mode in order to light an led, since the cc mode sign in the display is difficult to see.
