TCA9555 Expansion Module IIC/I2C GPIO Expansion Board Module

Detailed Information About The Product:

1. Multi-Channel Expansion: The module offers multiple configurable input/output channels, allowing you to expand a single I/O pin into many.
2. Digital Input/Output: This expansion board supports both digital input and output, enabling you to input external signals into a microcontroller or output signals from the microcontroller to external devices.
3. Low Power Consumption: Designed with low power consumption in mind, this muti-channel expansion board minimizes power usage during operation, making it ideal for applications requiring long-term use and extended battery life.
4. Programmable Features: The expansion module is highly programmable, allowing you to set the working mode, polarity, and current drive capability of input/output channels through configuration registers.
5. High Reliability and Stability: Built with premium components and reliable circuit design, this expansion module ensures high reliability and stability for your projects.

Type: Module
Condition: New
The operating voltage of is 1.65V to 5.5V,
J1-J2 single row pin spacing: 800mil (2.54mmx8=20.32mm).Suitable for access to breadboards.
All 16 IO ports have LED indicators.
The LED is designed with a common anode and uses a 2k resistor to limit the current; when the output of the IO port is logic 0, the LED lights up.
