??   Not true.  The Analog Discovery digital inputs handle 5V just fine and according to the reference manual they can tolerate up to +/- 20V.  The scope can handle up to 50V  or +/-25V.

Of course it is more fragile than a stand alone MSO, but it can do more within its frequency and voltage limitations. It’s really an ideal tool for Arduino or almost any breadboard range voltage or frequency projects.

An MSO such as my Instek MSO-2204EA is 300 V on the analog channels and 40 V on the digital channels.  Those ratings seem to be the norm for Rigol, Siglent etc.

Digilent lists the AD2 With a 16-channel digital logic analyzer (3.3V CMOS and 1.8V or 5V tolerant).
I have used my AD2 with 5 volt logic circuits with no problems at all.
The Analog Discovery really is the Swiss Army Knife of hobby or educational test & measurement equipment. When I eventually get a stand alone DSO and AWG I expect to keep the AD for its excellent logic, Spektrum, network and impedance analyzer capabilities.

Yes, it really is. I have a proper MSO (an RTB2004) on my lab bench,but I still use my AD all the time at my desk for quick breadboard or Arduino or TI launchpad projects. It also is an essential part of my travel kit.

What's your usual travel kit, out of curiosity?

Funny you should ask..

I put it together for that trip and used it a few times -though not as much as I’d liked to have.  I’m taking it with me tomorrow as I’m working a 24 hour shift and I hope to have some down time.
