The Pololu A-Star 32U4 Prime is a general-purpose programmable board based on the ATmega32U4 AVR microcontroller from Microchip arranged in the common Arduino form factor of the Uno R3 and Leonardo. It's compatible with many Arduino shields, including all of the majority of the Arduino shields we carry. All 26 of the microcontroller’s GPIO lines are accessible on the board, including seven that can be used as PWM outputs and twelve that can be used as analogue inputs. The ATmega32U4 is capable of native full-speed USB, which makes it more versatile than similar boards that rely on USB-to-serial adapters: in addition to supporting a virtual (CDC) serial/COM port interface, the A-Star can appear to a connected computer as a mouse and keyboard. The A-Star’s USB interface can be accessed through its USB Micro-B connector.

The A* Prime supports the onboard microcontroller with many additional features and improvements over competing products, including enhanced connectivity and superior power management. The Prime is available in two main versions: LV, which features a blue solder mask and a step-up/step-down voltage regulator that allows operation from 2 V to 16 V.
