Description
Description 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 digital/analog signal acquisition and light/servo control. Features 8-channel input/output expansion: Digital input/output ADC input SERVO control (PWM) RGB LED control I2C communication interface: Supports I2C address configuration Includes 1 x Unit EXT.IO2 1 x HY2.0-4P Grove connection cable (20cm) Applications IO expansion Servo control Multi-channel light control Multi-channel analog signal acquisition Specifications Specification Parameter MCU STM32F030F4P6 Communication Interface I2C @0x45 Number of IO Expansions 8 IO Interface Pin Spacing 2.54mm IO Supported Modes Digital input/output, ADC, SERVO control, RGB LED control IO Supported Input/Output Level 3.3V Product Size 32.0 x 24.0 x 10.2mm Product Weight 5.0g Package Size 138.0 x 93.0 x 11.2mm Gross Weight 10.0g Learn and Documents → DOCUMENTS
