A-Star 32U4 Mini LV Other Matrices the PT type of RTDThe A Star 32U4 Mini LV is a programmable module based on the ATmega32U4 from Atmel. Unlike competing products, it has an onboard switching step up step down regulator that allows it to be powered efficiently from a 2. 7 V to 11. 8 V supply. This compact 1. 9 0. 7 board breaks out all 26 of the microcontrollers I O pins (of which 7 can be used as PWM outputs and 12 as analog inputs), and loading programs is made easier by a Micro USB interface and a
