M5Stack Extend I/O 2 Unit (STM32F0)

Description:

EXT.IO2 is an IO extended unit that expands the input/output capabilities of a system. It is built around an STM32F030 main controller and utilizes the I2C communication interface for seamless integration with other devices. The EXT.IO2 provides 8 IO expansion ports that offer versatile functionality.

Each IO port on  EXT.IO2 supports independent configuration, allowing users to select from various modes such as digital I/O, ADC (Analog-to-Digital Converter), SERVO control, and RGB LED control. This flexibility enables the unit to handle multiple types of digital and analog signal acquisition tasks, making it suitable for a wide range of applications.

One of the key features of  EXT.IO2 is its ability to configure the I2C address of the device. This feature allows users to mount multiple EXT.IO2 units on the same I2C bus, expanding the IO resources even further. By assigning different addresses to each unit, users can easily manage and control multiple EXT.IO2 units in their system.

EXT.IO2 is well-suited for applications that require digital and analog signal acquisition, as well as lighting and servo control. It can be integrated into systems where additional IO ports are needed, enabling the acquisition of various types of signals and offering control capabilities for devices such as servos and RGB LEDs.
