|
|
|
|
The XL9535 component allows you to use **XL9535** I/O expander in ESPHome.
|
|
It uses :ref:`I²C Bus <i2c>` for communication.
|
|
|
|
Once configured, you can use any of the **16** available 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.
|
|
|
|
.. note::
|
|
|
|
This I/O Expander chip is used in the *Lilygo T-RGB 2.1" Round Display*
