About the product
- I2C interface based I/O expansion module, using 2 I/O can expand 8 I/O (more than 8 PCF8574 can be used at the same time, expand to 64 I/O)
- Support two interface types to access the target board: row of pins or row of holders
- Supports I2C bus cascade (multiple I2C modules can be used at the same time through the method of pin and socket docking)I/O expansion for MCU with tight I/O resources
- PCF8574, I2C interface, 8-bit parallel port
- Applicable to a variety of platforms including AVR / ARM
