QIO QOUT DIO DOUT

ESP32

Device Flash ID Fastest Mode
ESP32-WROOM-32D 204016 DIO
Shelly Plus 1PM 204016 DIO

ESP8266

Quad modes (QIO and QOUT) need GPIO 9 and 10. If device uses GPIO 9 or 10 with any function, possibles modes will be only DIO and DOUT.

All devices with an ESP8285 chip supports only DOUT mode because flash is integrated into ESP chip.
