Bảng Mạch Mở Rộng Pcf8574 Io I / O I2C-Bus Evaluation

PCF8574 IO Expansion Board I/O Expander I2C-Bus Evaluation Development Module Features: 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) #PCF8574 #IO #Expansion #Board #I/O #Expander #I2C-Bus #Evaluation #Development #Module
