Description:
PCF8575 I2C I/O Expansion Board Provides 16 Extra Programmable Input/Output Ports to Extend I/O Capacity for Microcontroller Development and Electronic DIY Projects
Features:
1. Stable Core Control: Built-in original PCF8575 main control chip, supports standard I2C communication protocol with low power consumption and high signal transmission stability, only occupies 2 I2C pins of your main controller to expand 16 additional I/O ports, greatly saving the I/O resources of your development board.
2. Durable Board Material: Made of high-quality FR-4 fiberglass PCB substrate, with excellent insulation, heat resistance and corrosion resistance, paired with gold-plated soldering pads to avoid oxidation, ensures long-term stable operation even in high-temperature or humid working environments, effectively extends the service life of the module.
3. Reliable Soldering Process: Adopts automated reflow soldering process for all SMD electronic components, ensures firm and uniform solder joints with low contact resistance, avoids poor contact and solder joint falling problems, reduces post-use troubleshooting and maintenance costs.
4. Convenient Wiring Design: Equipped with standard 2.54mm pitch tin-plated copper pin headers, provides low-loss electrical connection and good compatibility with common wires and breadboards, allows you to complete wiring quickly, shortens your project development and testing cycle.
5. Wide Compatibility: Adopts wide voltage input circuit design, supports 2.5V to 5.5V operating voltage, perfectly compatible with most mainstream microcontroller platforms including , Raspberry Pi, STM32 and ESP32, meets the I/O expansion demands of various DIY electronic projects, industrial control systems and IoT devices.
