I connected up the AD2 to RaspberryPi 3B+ and using an external 5V 3A power supply through a 2.1mm jack (TENMA bench PSU) but still got the error messages:

"Auxiliary supply undervoltage (3.14V) Please connect 5V DC 2.5 switching PSU"

I got the scope section working, but when I turn the Waveform generator on the error comes up.

Any suggestion?

Many thanks (koszi)
