Sobre este producto
- Electronics/Computers/Accessories/Computer Components/Single Board Computers
- 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)).
- Based on the I2C interface expansion modules, using I O can expand I O (up to simultaneous use PCF8574, expanded to 64 O).
- Support two interface types access target board: Pin or row seat.
- 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.

As the I/O interface resources of MCU is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C expansion board, you can easily implement functions that require many I / O interfaces. It is fantastic for MCU based project. Technical Specifications: Operating voltage: 2.5 V to 6 V with non-overvoltage tolerant I/O held to VDD with 100 uA current source Operating temperature: -40~85 Celsius Low Standby-Current Consumption of 10 μA Max I2C to Parallel-Port Expander 100 kHz I2C-bus interface (Standard-mode I2C-bus) Open-Drain Interrupt Output Compatible with Most Microcontrollers Latched Outputs with High-Current Drive Capability for Directly Driving LEDs Latch-Up Performance Exceeds 100 mA If you need sample programs or data manuals, you can contact us by mail, we will send you as soon as possible. Package Included: 5x PCF8574 I2C Interface 8bit IO MCU Expansion Board
