ESP8266 Capteur d'ozone

Peripherals - Tasmota

The ESP8266 and ESP8285 have 17 GPIO pins (0-16) but several are reserved or have constraints. Do not use any of the reserved pins. If you do, you might crash your program. On the ESP8266, six pins (GPIO 6 - 11) are used to interface the flash memory (the small 8-legged chip usually right next to the ESP8266).
