Custom PCB ESP32-C3-Mini not working

Dear Support, I need your help to find some guidelines to discover my mistake. I have made some PCBs based on typical application circuit of the module ESP32-C3-Mini with some minor modifications: a pushed button (SW3) on IO9 and a capacitor (C3) of 1 µF instead of 0.1 µF. shema for support.png The ...

ESP32-C3 Mini vs Wroom antenna performance

ESP32-C3-MINI-1 and ESP32-C3-WROOM-02 are equivalent, the first is integrating the flash in the package while the second is integrating the flash in the module. I have noticed that antenna dimensions are also different which may raise the question, do we have an impact on the RF performances of the ...

Re: ESP32-C3 Power Consumption during deep sleep

Hi @ESP_Sprite,
After scrapping the RGB Led (WS2812), the current went down to down to 61µA... :D :D :D
You were correct, Thank you

ESP32-C3 Power Consumption during deep sleep

Did any one truly measured current consumption during deep sleep of ESP32-C3 ? According to datasheet, it should be around 5 µA, but so far I was not able to find anyone to confirm this. I have made several research and tests and the output is the following: If you are using a dev kit board, choose ...

Re: ESP32-C3 power consumption doesn't match to the datasheet

Is there any update on this topic ? I am facing the same issue, using ESP32-C3-DevKit02, power supply directly on the 3.3v (to avoid LDO Regulator consumption and any other components connected to 5v). Result is a consumption of ~500 µA in deep sleep, significantly above the 5µA of ESP32C3WROOM02 da...
