A-Star 32U4 Prime SV (SMT Components Only)

Description

• A-Star 32U4 Prime SV (SMT Components Only)
• Supports 26 GPIO lines with PWM and analog inputs
• Operates efficiently from 5V to 36V sources
• Incorporates advanced power management system
• Offers native full-speed USB interface
• Preloaded with Arduino-compatible bootloader

The A-Star 32U4 Prime SV (SMT Components Only) is a versatile programmable board designed around the ATmega32U4 AVR microcontroller, arranged in the widely recognized Arduino form factor. This particular configuration is tailored for users who prefer to customize their assembly, as it excludes microSD support and through-hole components. The board is compatible with numerous Arduino shields, leveraging the microcontroller’s 26 GPIO lines, which include PWM outputs and analog inputs.

A notable feature of the A-Star 32U4 Prime SV is its advanced power management system, which supports efficient operation from a 5 V to 36 V external source. The board utilizes a switching step-down regulator to maintain a stable 5 V output, ensuring reliable performance across various input voltages. This configuration is ideal for projects requiring a robust power supply, as it can seamlessly switch between power sources while providing overcurrent protection.

The A-Star 32U4 Prime SV is equipped with a native full-speed USB interface, allowing it to function as a virtual serial port, mouse, or keyboard when connected to a computer. This enhances its versatility compared to boards relying on USB-to-serial adapters. The board is preloaded with an Arduino-compatible bootloader, facilitating easy programming through the Arduino environment.

Note: Batteries can have much higher voltages than their nominal voltages when fully charged, so be cautious with nominal voltages above 24 V. A 36 V battery is not suitable for this product.
