PCF8574 I2C Interface 8bit IO MCU Expansion Board I/O Expander I2C Bus Evaluation Development Module AVR STM8 C8051F For Arduino
Product introduction:
Function introduction: It is a big feature: typical application: main resources: data includes:
I / O expansion module based on I2C interface, using 2 I / O can expand 8 I / O (it can use 8 at the same time, expand to 64 I / O)
1. Support two types of interface to access the target board: pin header or row seat
2. Support I2C bus cascading (multiple I2C modules can be used at the same time through the method of pin header and row docking)
I / O expansion for MCUs with scarce I / O resources
, I2C interface, 8-bit parallel port
Test procedures (AVR, STM8,)
