Hello,
I have a defective ESP32 -S2-Saola-1 Devkit and now need a replacement.
In Germany I can currently only find the ESP32 Wroom version.
Are the pin-outs and the design the same?
I have the ESP32-S2 Saola on a circuit board and would like to be able to continue using the old wiring and my ESPhome code.
The old ESP32-S2 Saola works somehow, but I don’t get a signal. If I connect it to the USB port directly on my PC, it can’t be found either.
Kind reagards

These details are well documented. ESP32-S2-Saola-1 - ESP32-S2 - — ESP-IDF Programming Guide v4.3 documentation
Thanks ,
I know this documentation. I’m just trying to find the right one because the ESP-S2-saola-1 is probably no longer being produced.
So there must be some kind of suitable replacement.
I’ve currently come across the ESP32-S2-mini-1 or the ESP32-S2-DevKit-N4R2. I think both of them should fit… I’m not interested in flash or RAM memory, just the same pin-outs, at least those that I can use as GPIOs. I have it plugged into a circuit board. If that doesn’t fit, I’ll have to throw away the whole circuit board
Sure, but can’t you compare development boards you find online?
Seems to be available here
Yes, the problem is difficult because… on some dealers i find
with
and
with
• Micro-USB-Anschluss
• ESP32-S2-MINI-1
• 4 MB Flash
• Tasten und LEDs
MCU
• ESP32-S2 embedded, Xtensa® single-core 32-bit LX7 Mikroprozessor, bis zu 240 MHz
• 128 KB ROM
• 320 KB SRAM
• 16 KB SRAM in RTC
the dealer told me, he get that informations direct from espressiff
mmmhh…
both have the same size, both have 42 pins
wow, but in USA… i need that in Europe… on amazon i find it now to, but for the double price
great,
I found it thanks to your links, but I wasn’t entirely sure. Since I couldn’t find enough information like a data sheet from my dealer here in Germany… to be on the safe side, I ordered the
ESP32-S2-DEVKITM-1-N4R2
and the
ESP32-S2-DEVKITM-1
I think the only difference between them is the RAM and flash memory size
Many thanks for your help
You might receive two identical boards 
As far as I know devkitM-1 has only that variant commonly available.
thats perfect information. Thanks a lot. Now i see the different … looks like only in PSRAM & External/Onboard Antenna
Just to clarify, as my English is not the best.
EOL means EndOfLife or ? right?
then you shouldn’t buy EOL products anymore
Bullshit, that isn’t the right board… oh my god…
both S2-saola and the devKit-M1 have different dimensions…
ESP32-s2-DevKit-M1-Dimensions
and there
ESP32-s2-saola-Dimensions
This component is defective on my ESP32-saola-1
Yes, EOL means end of life.
That sucks! You might find some headers with 2.54mm offset.
The component you pointed is 3.3V voltage regulator. If that is the only damaged component you can still power Esp directly from 3.3V pin with external 3.3V source.
But it also means you probably have something wrong on your circuit board. Either drawing too much current or power supply problem. Those voltage regulators are quite robust if not abused.
