The LP Mini is an Arduino Pro Mini compatible development board for low power applications. Besides using a less power-hungry voltage regulator, it features a real time clock for waking up its ATmega328 and a mosfet to turn external devices on and off. With a sleep current of only 2.8 µA (@3.3V), the LP Mini is ideal for data logging over extended periods of time.
