ESP32s and ESPHome

[juan (jjprz)]

Hello friends!
A few days ago I bought an ESP32 development board. It must be a different version than the ones I see in tutorials to install ESPHome (ESP32S ??) I have a usb ttl board to connect it to the PC and flash it but I don’t know how the cables are placed. Could you tell me how to install ESPHome on this board?
Thanks in advance!

You don’t need the USB-TTL cable. See the USB mini connector on your board?

Just use USB mini to USB A cable to connect the board to your Home Assistant / PC USB port.

Also for ESP32’s there is a specific sequence you must follow for the bootloader:

Having problems with ESP32

Are you running windows on your laptop? If so this utility is is handy for notifying you of new com ports without having to drill down into device manager: https://helmpcb.com/software/serial-port-monitor It can be tricky to get ESP32s into boot mode. i) Power on / connect the ESP ii) Start the flash tool connecting iii) Press and hold both buttons on the ESP board iv) Release the EN button while continuing to hold the IO0 button v) When the flash tool discovers the device you can relea…

On your board the IO0 button is labelled “BOOT”.

Thank you very much @tom_l . The solution you indicated worked. In my case, an extra step was missing for it to recognize the port. Install the driver I found on GitHub. https://github.com/esphome/esphome-flasher/issues/45
