Now i have the results from the oscilloscope: No voltage drop at all - same error.
Do i have a faulty module? Should i return it to my reseller? Any other ideas what to do?
Are the measurements from my previous post in spec?
Thanks in advance!

Re: Can't get ESP32 WROOM to work with any example
Hi Angus, i didnt have time today at work to measure the module with the oscilloscope so i will try again tomorrow. While i was going to measure the EN-Reset current i noticed that the error type now changed from IllegalInstruction to InstrFetchProhibited with following output: ets Jun 8 2016 00:22:...

Re: Can't get ESP32 WROOM to work with any example
As suggested i tried again with one of those WIMA 2.2µF caps (see picture from Hans) directly soldered to the power pins of the ESP32. Unfortunately this didn't make any difference either - i still get the exact same error message from my initial post. I'll bring the ESP32 to the Lab tomorrow and ho...

Re: Can't get ESP32 WROOM to work with any example
Hi Angus, the power supply can deliver up to 2A @ 0-15V and is set to ~3.33V. IMAG0144.jpg Setup on breadboard is following: (Caps are 470uF and 100nF) IMAG0145.jpg I also tried to solder the power pins directly to the power supply. Doesn't help. As i also tripple checked all solder pins of the ESP3...

Can't get ESP32 WROOM to work with any example
Hi, i spent the last couple of days trying to get any of the ESP32 Arduino examples to work. I got a ESP32 WROOM module on a simple breakout board. Connecting through standard USB->serial bridge. Circuit is very basic: EN pin connected via 22k to 3.3V, external power supply set to 3.3V, bunch of buf...
