Youmile 5 pcs PCF8574 IO Expansion Board PCF8574 I/O Expander I2C Evaluation Develop Module with DuPont Cable for Arduino & Raspberry Pi

• 【Remote expansion】: 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)).
• 【Multiple expansions】: Based on the I2C interface I / O expansion modules, using 2 I / O can expand 8 I / O (up to 8 simultaneous use PCF8574, expanded to 64 I / O).
• 【Interface type】: Support two interface types: Pin or row seat to access the target board
• 【Special design】: 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.
• 【Widely used】: Applicable to a variety of platforms including AVR STM8 C8051F for Arduino.
