3pcs M5Stack® Extend Serial IO I/O Module Grove I2C Interface Expansion Board for Arduino ESP32 Development Board Module IoT
Description:
EXT.IO is a GPIO Expander. With simple I2C commands you can have up to 8 GPIOs.
Integrates PCA9554PW. This 8-bit I/O expander for the two-line bidirectionalbus (I2C) is designed for 2.3-V to 5.5-V VCC • Open-Drain Active-Low Interrupt Output operation. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface.
IIC address: 0x27.
It’s difficult to foresee the needs of your project from the start. EXT.IO is the perfect solution for expanding the number of IO. It allows you to add new features, logic,timing and sensing to alrady highly integrated designs.
