12PCS PCF8574 IO MCU Expansion Board I2C Interface 8bit I/O Expander IIC Bus Evaluation Development Module
Description
I2C interface, I / O expansion module, two I / O scalability 8 I / O (up to 8 simultaneous use the PCF8574 expanded to 64 I / O) Most important feature: 1. Supports two interface types access target board: Pin or row seat Support I2C bus cascade (by pin header row seat docking methods can be used simultaneously multiple I2C modules) Typical application: I / O resource shortage MCU I / O expansion Main resources: the PCF8574 I2C interface, 8-bit parallel Information includes: Test procedures (AVR, STM8, C8051F) Circuit schematics Related PDF data Package Included: 12 x PCF8574 IO Expansion Board
Features:
- The PCF8574 IO Expansion Board provides general-purpose remote I O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA).
- PCF8574 IO expansion board with I2C interface, I / O expansion module, two I / O scalability 8 I / O (up to 8 simultaneous use the PCF8574 expanded to 64 I / O)
- PCF8574T PCF8574 IO expansion board support I2C bus cascade (by pin header row seat docking methods can be used simultaneously multiple I2C modules)
- This 8-bit input output (I O) expander for the two-line bidirectional bus (I2C) is designed for 2.5-V to 6-V VCC operation.
- PCF8574T expansion board applicable to a variety of platforms including AVR / ARM
