I2c port expander
WebbThe Arduino acts as a port expander, allowing you to use more pins than a standard ESP8266/ESP32 has. The Arduino is connected to the ESP via I²C. Most Arduinos use the A4 and A5 pins for the I²C bus so those pins are not available to read from ESPHome. It is recommended to use a 3.3V I/O level Arduino, however using 5V Arduinos seems to … WebbProduct Details. 400kHz I 2 C Serial Interface. +1.71V to +5.5V Operating Voltage. 8 Open-Drain I/O Ports Rated to 20mA Sink Current.
