[EOL] Extend Serial I/O Unit (PCA9554PW)
Description
Unit EXT.IO is a parallel port expander. It integrates the IO expansion chip PCA9554PW, supporting expansion to 8 GPIOs, and can be used for 2.3 ~ 5.5V VCC, open drain, pull-up, and interrupt output operations. Through the I2C interface (serial clock SCL, serial data SDA), it assists most microcontrollers in providing I/O expansion. For developers who are short on I/O pins and do not want to waste resources by adding extra controllers, Unit EXT.IO is a good assistant.
