@ -146,6 +146,9 @@ pins for your projects. Within ESPHome they emulate a real internal GPIO pin
and can therefore be used with many of ESPHome's components such as the GPIO
binary sensor or GPIO switch.
GPIO pins in the datasheet are labelled A0 to A7 and B0 to B7, these are mapped
consecutively in this component to numbers from 0 to 15.
