Product Description
HiLetgo 2pcs PCF8574 PCF8574T IO Expansion Board I/O Expander I2C Evaluation Develop Module
- PCF8574T IO Expansion Board
- The main resources: PCF8574, I2C interface, the 8-bit parallel
- Typical applications: for I / O resource constraints the MCU I / O expansion
- Maximum Features: supports two types of Interface
- access to the target board: Pin or row seat
Description:
Based on the I2C interface I / O expansion modules, using two I / O can be extended to eight I / O (up to simultaneous use 8 PCF8574, expanded to 64 I / O)
Maximum Features: supports two types of Interface, access to the target board: Pin or row seat
2 supports I2C bus cascade (via pin, row seat docking methods can be used simultaneously multiple I2C modules)
Typical applications: for I / O resource constraints the MCU I / O expansion
The main resources: PCF8574, I2C interface, the 8-bit parallel
