ESP32 Forum

I have looked a lot around the web and cannot find an answer to this question.
How much power is available at the 3.3v pin for driving attached devices,
Like LCD, relay etc given 5v is applied to the 5v pin?

The schematic says the LDO on that devboard is a SGM2212-3.3XKC3G/TR and the datasheet for that part says it can provide 800mA. The datasheet for the ESP32-S3 says you want to have at least 500mA reserved for that chip, leaving 300mA for anything else you want to feed from the 3.3V rail.
