PWM Pins. Every GPIO pin on the ESP8266, spanning from GPIO0 to GPIO15, is programmable to generate pulse width modulated (PWM) outputs. The PWM signal on the ESP8266 boasts a 10-bit resolution, offering precise control over the output.
ESP8266 Pinout Reference: How To Use ESP8266 GPIO Pins
Software PWM is supported on all GPIO0 through GPIO15 pins by the ESP8266. We can adjust the frequency range of the ESP8266 from 1Hz to 1KHz, generating a PWM signal with 10 bits of resolution. Example: Read the analog value from A0 and apply the corresponding PWM signal to D6 to increase/decrease an LED’s light emission.
ESP8266 Software PWM Output - ESPHome
The ESP8266 Software PWM platform allows you to use a software PWM on the pins GPIO0-GPIO16 on your ESP8266. Note that this is a software PWM, so there can be some flickering during periods of high WiFi activity. Hardware PWMs like the one on the ESP32 (see ESP32 LEDC Output) are preferred.

Pin numbers in Arduino correspond directly to the ESP8266 GPIO pin numbers. pinMode, digitalRead, and digitalWrite functions work as usual, so to read GPIO2, call digitalRead(2). Digital pins 0—15 can be INPUT, OUTPUT, or INPUT_PULLUP. Pin 16 can be INPUT, OUTPUT or INPUT_PULLDOWN_16. At startup, pins are configured as INPUT.
