We have found during EMC testing that the ESP32-C3-Mini module stops communicating via Wi-Fi when subject to external interference at 3V/m. The frequencies that cause the issue are in the range 2.15Ghz to 2.28Ghz and 2.5Ghz to 2.8Ghz. The 2.28Ghz to 2.5Ghz range is an exclusion band due to the delib...

Thanks for looking into this. Useful to know both the theoretical and practical limit.

I am only planning on using it at maximum 6.5V, probably less. So I should be good!

Is the maximum supply voltage for the ESP32-C3 Devkits specified anywhere? It would be useful to know the maximum voltage that can be applied to the 5V pin. I have tried looking up the regulator used on the board but I can't find its datasheet.

Many thanks!
