Supports I2C and SPI through USI interfaces, enabling flexible communication with a wide range of sensors and peripherals. Power options include USB or an external supply. Accepts 716 V input and automatically regulates to 5 V for convenient operation in different environments. PWM on 3 pins, with additional PWM possibilities available through Software PWM. Suitable for LED dimming, motor control, and other timingsensitive applications. 8 KB memory (about 6 KB available for user code after bootloader). Provides space for typical microcontroller projects and firmware. Use scenarios Sensor hub for environmental monitoring: Connect multiple I2C and SPI devices such as temperature, humidity, and pressure sensors to collect and process data on a single board. Small robotics or LED projects: Use PWM outputs to control motor speed or LED brightness, enabling smooth transitions and reliable control in compact builds. Prototyping and development: Power the board via USB for easy desktop testing or via external supply for portable setups; leverage the bootloaderusable memory to iterate firmware quickly.
