Re: PCB (or commercial product) with ESP32 + Power Supply + Relay

Re: [help]spi pin number

They (gpio 6-11) can be used for parallel spi operations in limited cases, hardware debugging, direct programming of the flash chip, possibly slave mode. We complained about the esp8266 modules that didn't break out these pins and eventually got esp-12e/f/d/q. To assume that a gpio is free and clear...

Re: Max current from a GPIO pin?

Re: Processing multiple interrupts sources

Oops didn't realize this was on the untested blacklist. You can disable the abort in menuconfig if you want to try it.

Re: Dea ESP-32S

What is voltage on flash vcc pin? Did you change flash clk speed, mode (dio/qio)? Is encryption enabled (check efuse)?
