Hi,
What's the difference between these two boards.
They look like exactly the same.
I must be wrong.
Thanks

Hi n47h4n,
The boards have a different on-board module and PSRAM size. For detailed comparison see:
- ESP32-S2-DevKitM -
https://docs.espressif.com/projects/esp ... nformation
- ESP32-S2-DevKitC -
https://docs.espressif.com/projects/esp ... nformation
In short, ESP32-S2-DevKitM boards compared to ESP32-S2-DevKitC boards are slightly smaller because they have smaller ESP32-S2-MINI on-board modules. The modules in turn are smaller because inside they have ESP32-S2 chip variants that already integrate flash and PSRAM.

Thanks @ESP_krzychb
8,74mm is a real difference indeed.
For the PSRam, I think it's the same. I was wrong when saying ESP32-S2-DevKitM-1, it was in fact ESP32-S2-DevKitM-1-N4R2.
Thanks again.

Hi @ESP_krzychb
After reviewing the 2 boards ,(I reviewed esp32-s3-devkitC-1 and esp32-s3-devkitM-1)
Aside from what u said , it is said that devkitC-1 has wroom-1 which is powerful compared to mini-1 found on devkitM-1,
also devkitM has more GPIOs available than devkitC, by removing some grounds pins and making them usable, and having only 1 ground pin.
Is what am saying valid ?? I'm new to microcontroller and might not fully understand the specs, that's why I'm asking.
