DFRobot μHex Low Power Controller (DFR0343)

Hexagonal ATmega328P board running at 8 MHz on 2.7–5 V, with 14 digital and 6 analog GPIO and 4 switchable power ports to cut supply to peripherals. Targets battery-powered applications; sleep current drops to 0.12 µA at 3.3 V (watchdog off), giving roughly 60 days on a CR2032.
