Anybody know of any SBCs* with good low power modes enough to run for a few days on a 4000 mAh battery?
Phones have been able to do this for years, but I can't find any modern Linux SBCs with real lower power CPU modes to last for days.
* ideally 1+GHz with 4GB RAM and on-board lipo charging circuit
- polartx 8y agoNot sure if this meets all those requirements, but check out the NanoPi Neo. I've run it on battery a few times, and it only cost $12
- ac29 8y agoThe recently released Linux 5.0 kernel supports energy-aware scheduling, which should help out with this: https://lwn.net/Articles/749900/ https://lwn.net/Articles/749900/
- voltagex_ 8y agoFinding a recent board that can run mainline kernels may be a challenge.
- bluegreyred 8y agoIndeed, that's what makes the raspberry pi so hard to beat, even though I'm just a hobbyist using it as a tinker toy. If something major breaks software-wise you can be pretty sure that the rPi community is large enough to produce a fix within hours. OTOH if you'd like a new kernel for that fancy $65 big.LITTLE 4GB dualchannel ECC Gigabit PCIe SBC then you're at the mercy of your vendor who considers 4.4 LTS ought to be good enough and already reassigned the entire dev team to work on a future hardware release. ¯\_(ツ)_/¯
