Description 1. PCF8575 I/O Extension Shield Module 2. Size: 25mm x 25mm 3. Not solder pin 4. If your IO port is not enough, then you can use the PCF8575 expansion board to expand more IO port. 5. Two lines, SDA, SCL can achieve 16 IO port input and output control, the use of very simple. I2C signal can be simulated by software, some comes with I2C interface, the microcontroller can be directly operated. 6. By setting A0 \\\\ A1 \\\\ A2 to set different I2C device address, up to 8 devices can be accessed, thus realizing 128 IO port expansion.
