Pololu item #: 3106
Brand: Pololu
Status: Discontinued 
RoHS 3 compliant

This product has been discontinued.

This original version (ac03b) of the A-Star 32U4 Prime LV has been replaced by a newer version (ac03e) with an improved 5V regulator that can deliver more current and has a wider 2 V to 16 V operating range.

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 includes microSD support and does not include any through-hole components; it is intended for those who want to customize the way it is assembled.

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.
