PCF8574 IO Expansion Board Expander I2C-Bus Evaluation Development Module Board
Based on the I/O extension module of I2C interface, 8 I/Os can be extended by using 2 I/Os (most of them can use 8pcs PCF8574 and 64pcs I/Os at the same time).
1. Supporting two types of interface access to the target board: Needle or needle row.
2. Supporting I2C bus cascade (multiple I2C modules can be used simultaneously through needle or needle row).
3. Typical Applications: I/O Extension for MCU with I/O Resource Shortage.
4. Main resources: PCF8574, I2C interface, 8-bit parallel port.
