A-Star 32U4 Prime SV microSD with LCD
The A-Star 32U4 Prime SV 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 5 V to 36 V. This configuration of the A-Star 32U4 Prime SV includes microSD support, preinstalled female headers common to many Arduinos, and a removable 8×2 character LCD.

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
- For light loads. The regulator's dropout voltage increases approximately linearly with the load, from a few millivolts at no load up to around 0.9 V at 1 A.
- 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.
