I'm working on a project that involves sending GPS coordinates wirelessly from an arduino board to another one. I was thinking of using an arduino micro for this task. The problem is that I want it to last as long as possible on a lithium battery. I searched and found too many tutorials on how to decrease arduino pro mini power consumption, but I didn't find anything related to the arduino pro micro. So I was thinking, does the same procedure used to decrease the arduino pro mini consumption apply for the arduino pri micro? Also, what microcontroller do you suggest for this project? (PIC, Arduino mini, micro, nano...)

  • how are you obtaining the GPS coordinates? – jsotola Jan 28 '18 at 8:44
  • Most techniques apply to all Arduino boards. Remove the power led. Put the microcontroller in sleep-mode. Possibly remove/exchange the voltage regulator. Put attached devices to sleep, or remove power to them entirely. – Gerben Jan 28 '18 at 17:18

Bringing Down power consumption by taking the LED out and lowering the clock ?

Yes, you can do that! And you are okay with Arduino unless you want to complicate things more...If you want to check out other methods then you can check out the Microcontrollers Schematics and also the datasheets of their Components...


The methods for arduino uno and pro micro are the same because they use the same architecture. Also i think that arduino and AVR is good for this project because of a big database of documentation for it more than for PIC :).

  • The Pro Micro uses an ATmega32U4. – Edgar Bonet Jan 28 '18 at 16:24
  • @EdgarBonet oh sorry I thought we where talking about an pro mini. – Coder_fox Jan 28 '18 at 16:44
