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This original version (ac03b) of the A-Star 32U4 Prime LV has been replaced by a newer version (ac03e) with an improved 5V regulator that can deliver more current and has a wider 2 V to 16 V operating range.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, preinstalled female headers common to many Arduinos, and a removable 8×2 character LCD.
