2016-06-23 at 10:18 AM #1583Right now I am trying to power the mayfly using a battery pack, but I am not sure how much power the Mayfly and all of it’s applications (XBEE port, SD card reader) consume. I am only concernedRight now I am trying to power the mayfly using a battery pack, but I am not sure how much power the Mayfly and all of it’s applications (XBEE port, SD card reader) consume. I am only concerned with powering the on board applications, since all external sensors have there own power needs. Are there any references to the power or current requirements for the board and how much is needed?

Yes, I’ve done a variety of power measurements with the Mayfly board, so I can publish a table showing the different options. I’ll put a link to it here when the page is posted.

Ok, that sounds good. By the way thank you for being so helpful with the switch error, everything is working fine now

2016-07-23 at 9:34 PM #1674I haven’t had a chance to make a table of all of the power usage data from my tests, but here are some of the more important measurements:
Mayfly current when board is powered and idle: 6.5 m
I haven’t had a chance to make a table of all of the power usage data from my tests, but here are some of the more important measurements:Mayfly current when board is powered and idle: 6.5 mA
Mayfly current when MCU put to sleep: 0.27 mA (or 270 uA)
Current when asleep with microSD card in the socket: 0.43 mA (or 430 uA) -

Hi Steve,
Can you provide a little bit of example code that demonstrates how to put the MCU to sleep?
Thanks

Cool, thank you Steve for the measurements, as these will provide enough information to approximate the size of battery I will need

2016-08-03 at 4:37 PM #1684For most of my loggers, I use a 1200mah or 2500mah battery, depending on how much power the external sensors draw, what size solar panel I’m using, and how shady the deployment site might be.For most of my loggers, I use a 1200mah or 2500mah battery, depending on how much power the external sensors draw, what size solar panel I’m using, and how shady the deployment site might be.
I’m optimizing and documenting the sleeping logger Arduino code and will post it as soon as it is ready.
