Description

All official Arduino boards are carefully designed boards with individual unique features. One of the feature that we were looking for was low power consumption. Mini Ultra 8 MHz was designed to fill this void. We also came out with an Arduino compatible low power library to allow flexible low power management of the board. If your next project needs to run on battery or without main power, this is the board you might want to consider! Supporting carrier and application specific boards are coming soon!

Specifications:

  • Compatible with Arduino IDE using “Arduino Pro Mini 3.3 V 8 MHz” as the board option
  • Microcontroller – ATmega328P-AU
  • Clock – External ceramic 8 MHz resonator
  • Operating voltage – 3.3 V
  • Low quiescent current (1.6 μA) on-board 3.3 V 250 mA regulator
  • Ultra low power – Minimum 1.7 μA in power down mode
  • External DC source range – 3.4 – 6 V
  • Indicator LED connected to digital pin 13 through a MOSFET
  • FTDI 6-pin header
  • Emphasis on low noise design approach
  • Analog reference voltage with LC filter
  • Digital pins (D0-D13) breakout on 1 side of the board
  • Analog pins (A0-A7) breakout on 1 side of the board
  • 600 mil in between 2 breakout headers - suitable for breadboard usage
  • Dimension – 18.41 mm x 39.37 mm (0.725″ x 1.55″)
  • RoHS compliant – Yes
  • Board came with pre-loaded firmware running in power down (refer to our low power library). You can measure the current consumption right away!
