Because GPIO0 is a strapping pin for entering UART flashing mode on reset, care must be taken when also using this pin as EMAC_TX_CLK. If the clock output from the PHY is oscillating during reset, the ESP32 may randomly enter UART flashing mode. One solution is to use an additional GP...
Suggest you find the circuit diagram for you board, it will show how the 5V pin are conneted to the usb input or you can try messure the resistens between the 5V pin and usb 5V in with an ohm meter. If direct conneted and/or there are zero ohm, it all depend on your usb ...

This is a input pin for ESP peripheral. This pin resets ESP peripheral and is mandatory in SPI based ESP-Hosted solution. Handshake pin ESP 的输出引脚。高电平表示正在进行ESP32正在通过spi接口和主机进行交互。因此,当该引脚是高电平的时候,主机不应该启动spi数据传输。通俗一点的解释就是:host想给ESP32...
