ESP32 Forum

Hi everyone,

I’m using the ESP32-S3-Touch-LCD-4 board and I’ve encountered an issue when trying to power it via 7~36V DC input.
• When I power it via USB Type-C, it turns on, and pressing the BAT_PWR button starts the demo.
• But when using 7~36V DC, the power LED and display turn on, but the ESP32 doesn’t boot.

Has anyone faced this issue before? Is there a way to configure it to boot automatically with DC input, or do I need to modify something (e.g., clearing the demo program, DC changes more than 9 or 12)?

Any help would be appreciated!

Thanks!

I believe that symptom is explained on their wiki for it.
I bought both Rev 1 and Rev2 (the rev number is under the LCD cable. Both have issues. Wound up chucking them both.
