ITEM NAME:PCF8574 IO Expansion Board I2C-Bus Evaluation Development Module Board #gib Product Description Description: PCF8574 IO Expansion Board Expander I2C-Bus Evaluation Development Module Board Description: 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). Feature: 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. Specification: Packaging size: 100mm*60mm*10mm/3.93*2.36*0.39'' Packing weight: 5g Note: Please allow 1-3mm differs due to manual measurement.
