--- Quote from: rhb on July 24, 2018, 02:31:42 am ---I should like to point out that the Analog Discovery is *very* fragile. It's far too easy to let the magic smoke out. You're limited to 25 V on the analog channels and 3.3 V on the digital channels. I'd be rather nervous connecting one to an Arduino without level shifters from 5 to 3.3 V. I should not want to find out what happens without the level shifters. --- End quote --- ?? 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. |

I should not want to find out what happens without the level shifters. 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. --- End quote --- 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. |

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. |

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. |
