M5Stack Extend I/O 2 Unit
The M5Stack EXT.IO2 is a powerful I/O expansion unit designed to enhance the input/output capabilities of your system. Built around the STM32F030 main controller, the EXT.IO2 utilizes the I2C communication interface, allowing for seamless integration with other devices and components.
This versatile M5Stack Extend I/O 2 Unit features 8 I/O expansion ports, each of which supports independent configuration. Users can choose 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, making it suitable for a wide range of robotics, automation projects, and DIY creations.
One of the key features of the M5Stack EXT.IO2 is the ability to configure the I2C address of the device. This feature enables users to mount multiple EXT.IO2 units on the same I2C bus, further expanding the I/O resources. By assigning different addresses to each unit, users can easily manage and control multiple M5Stack EXT.IO2 units in their system, making it a scalable solution for complex projects.
The M5Stack EXT.IO2 is ideal for applications that require digital and analog signal acquisition, as well as lighting control and servo motor control. It can be integrated into systems that need additional I/O ports, enabling the acquisition of various signal types and providing control capabilities for devices like servos and RGB LEDs.
