Low power Arduino Pro Mini board

3317771479151537261.JPGMax.K created this Arduino Pro Mini compatible development board for low power applications:

LP Mini

ideal for data logging over extended periods of time [..] can run for months or even years on a coin cell

9921941479300894867

Hardware

  • Microcontroller: Atmega328p with Arduino bootloader
  • Real Time Clock: MCP79410
  • Voltage Regulator: MCP1700
  • FDN340P MOSFET

Features

  • 2.8 µA current consumption in sleep mode
  • Compatible to the Arduino Pro Mini (except for pin 2 and 10)
  • A real time clock keeps the time and is used to wake the Atmega from sleep mode
  • Sleep current is reduced by using a more efficient voltage regulator
  • A simple Mosfet is used to turn external devices on and off if the IO pins cannot provide enough current
