Hi, NooB Here.

Trying to program the ESP32 in PlatformIO:

1. Which ESP32 S3 chip should I configure when creating the project in PlatformIO?

2. How do I make it connect to upload? Do I need to hold a button before uploading? I tried holding the DL button but it didn't connect. Same for the RST button.

Thanks

Can I use 24V DC instead of 230V AC on relays?

I would like to use them to activate my 24VDC activated contactor (and then contactor would let 230V AC to pass through).

Hi, All

If to use it by default only for relay control - what is the power consumption from 12VDC source ?
Also A4 and A6 models this info is needed (default power consumption).

I want to connect HC-SR04 to GPIO02 and GPIO15, but ESP does not see it
