The A-Star 32U4 Prime LV is a programmable board based on the ATmega32U4 AVR microcontroller and arranged in the common Arduino form factor. The A-Star Prime offers many additional features and improvements over competing products, including superior power management that enables efficient operation from 2 V to 16 V (though it requires at least 3 V at start-up). This configuration of the A-Star 32U4 Prime LV includes microSD support and preinstalled female headers common to many Arduinos.

Other PCB markings: 0J11918

Notes:

1
Note that 4 KB of the MCU's 32 KB of flash memory is used by the pre-installed USB bootloader. All 32 KB is available when programming via the ISP header rather than the bootloader.
2
Note: the minimum startup voltage is 3 V, but the regulator can operate down to 2 V after startup.
3
Available current depends on input voltage, current consumed by the board, ambient conditions, and regulator topology. See product documentation and performance graphs for details.
