Extend I/O 2 Unit (STM32F0)

Unit EXT.IO2 is an IO expansion unit developed based on the STM32F030 main controller, using an I2C communication interface, providing 8-channel IO expansion. Each IO channel supports independent configuration of digital input/output, ADC, SERVO control, and RGB LED control modes. It supports configuring the device's I2C address, which means users can mount multiple Unit EXT.IO2 units on the same I2C bus to expand more IO resources. It is suitable for applications such as multi-channel… (M5Stack U011-B)
