Low powered board with gpio working

[technik007_cz]

Hi guys, I am looking for cheap device alternatives capable running on battery. It must be low power consuming. Any ideas?

Maybe not very useful but banana pi M1 (I guess also other variants) is able to run on ac/battery.

You just have to find the specs of the board you are interested in and check if it has a power charger chip and connections for battery.

 

Or you can make a micro-usb connector for your battery and most of the boards will work.

 

Power consumption will depend on the board and -what- is installed. So less services running = more battery

I am trying Banana Pro now. I found root ssd drive connected in usb do not work. But I have been using power bank box with soldered wire to Banana Pro board. I tried plug root sata drive into power bank usb hole and yea it is working together. I found later on aliexpress powerbank for 18650 batteries with switch. So I will be able to easily power off Banana Pro and when I will not see power lights I can switch off safely root ssd drive.

I hope you don't try to run that board or in fact any board from AC, feed AC into these boards and you will see smoke for sure !

All these sort of boards do not have on-board AC to DC power supply built on the board, they all require a nice clean source of DC power.

 

technik007_cz, most ARM based boards are usually fairly efficient on power.

It will be peripheral devices that will account for the major increase in power consumption, things like a GPU or other video hardware.
