PCF8574 I2C to 8-Bit Digital IO Port Extension Module โมดูลขยายพอร์ด IO Arduino ผ่าน I2C This module (HCMODU0120) is a breakout board for the PCF8574 8-bit input/output (I/O) expander IC. Using this module you can expand the available digital I/O pins of your microcontroller via its serial I2C interface. The device features an 8-bit quasi-bidirectional I/O port (P0P7), including latched outputs with high current drive capability for directly driving LEDs. Each quasi-bidirectional I/O can be used
