The A-Star 32U4 Prime SV microSD is a versatile programmable board designed around the ATmega32U4 AVR microcontroller, adopting the widely recognized Arduino form factor. This configuration includes microSD support and preinstalled female headers, facilitating compatibility with numerous Arduino shields. The board's power management system is a standout feature, allowing efficient operation from a wide voltage range of 5 V to 36 V, regulated by an ISL85410 switching step-down converter. This ensures stable performance and the ability to power additional devices.

The microcontroller offers native full-speed USB capabilities, enabling it to function as a virtual serial/COM port interface and emulate a mouse or keyboard when connected to a computer. This enhances its versatility compared to boards relying on USB-to-serial adapters. The board provides access to all 26 GPIO lines, with seven available for PWM outputs and twelve for analog inputs, making it suitable for a variety of applications.

The A-Star 32U4 Prime SV is equipped with a preloaded Arduino-compatible bootloader, simplifying programming through the Arduino environment. It shares the same microcontroller and form factor as the Arduino Leonardo, ensuring compatibility with shields designed for similar boards. Additional features include user-controllable LEDs, pushbuttons, and a buzzer option for sound generation. The board can be powered via USB or an external source, with a power selection circuit for seamless switching between power inputs.
