Clearance: This product is being replaced by a newer ac03e version with an improved 5 V regulator that operates from 2 V to 16 V and can deliver more current.
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 2.7 V to 11.8 V. This configuration of the A-Star 32U4 Prime LV has no microSD support and includes preinstalled female headers common to many Arduinos.

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
- Available current depends on input voltage, current consumed by the board, ambient conditions, and regulator topology. See product documentation and performance graphs for details.
