Product Description
Features:
· The PCF8574 IO expansion board provides universal remote I/O expansion through a two-wire bidirectional I2C bus (serial clock (SCL), serial data (SDA)).
· Support two interface types to connect to the target board: pin header or socket
· Support I2C bus cascading, multiple I2C modules can be used at the same time through the method of pin header and seat docking
· I/O expansion module based on I2C interface, using 2 I/O can expand 8 I/O
· A wide range of applications: compatible with various platforms including AVR STM8 C8051F Arduino.
