Power Draw Comparison: Artemis Thing Plus, Artemis Nano, expLoRaBLE

Development Boards Other Microcontrollers
1

I am interested in the power draw figures for the Artemis Thing Plus, Artemis Nano, and expLoRaBLE for a battery powered project. I see in the microcontroller selection [guide that the Artemis Nano uses <5mW in full operation. I hope that’s for the whole board and not just the Artemis module, but I saw the OpenLog Artemis is 20mA, so I wanted to be sure.

  1. What does full operation mean? Is that when idle but a non-sleep mode such as running a loop with just delay(1);

  2. Does the Artemis Thing Plus have the same power draw figure?

  3. Does the expLoRaBLE, which also has the Apollo3, have the same power draw figure? I know the radios are different, so aside from that.

Power draw stats on your comparison page would be useful for choosing between microcontrollers for battery powered systems.](https://www.sparkfun.com/advanced_arduino_comparison_guide)

Any help? If low power is the great appeal of Apollo then these numbers are critical!

help?

I found values for the Artemis Nano in this thread. https://forum.sparkfun.com/viewtopic.php?f=172&t=50789

As discussed in that thread, a true low power board would be incredibly useful for many projects from science, to cosplay, to industrial, to home automation. The great 2.5mA figure for the running artemis nano is undercut by the very high 2mA sleep current

Power draw is dependent on the code you’re running and how you power your board as well as what’s connected too it.

The only thing I can suggest is to measure it yourself under your operating conditions. That’s the only way you’re going to get useful, accurate results.
