| ESP8266 | ESP32 |

Please note that the numbers IOxx for the ESP32 correspond to the GPIO numbers.

So..., IO22 corresponds to GPIO 22.

The same is *not* valid for the numbers Dx in the ESP8266 case.

Please see the next slide for the correspondence.

---+ Comparison !PinOut <br />ESP8266 versus ESP32 for reference
