I'm attempting to use a bunch of OrangePi Zeros for a low power sensing application.
I have an OrangePi Zero 512M which I started developing on. It works extremely well and with the GPU/ethernet off and CPU/Ram underclocked it operates at about 30-34 degrees C, using only a tiny amount of power.
I recently got a bunch of OrangePi Zero 256M models, I've tried three of them now and (either a fresh install of the same version of Armbian or the exact same SD card as the 512M is running on) they all run around 55-60C at idle and overheat/freeze when attempting to install packages or compile.
Any ideas? Is there some setting I could have changed that lives on the SoC or flash rather than SD card that accounts for the lower power use?
And the funny thing is that this PDF had to be sent around the globe one time to arrive finally where it is now: https://github.com/OrangePiLibra/OrangePi_H5SDK/issues/1#issuecomment-262170906. (I got it from Igor who got it from Steven I suppose)
Even more funny that Jens managed to get preliminary mainline u-boot support working even before the user manual had been released: https://github.com/jemk/u-boot/tree/apritzel-h5-dram
