Anyone staking using an atomic pi? Looks like a pretty low cost and low power solution to have your staking wallet on all the time.
I am staking on a RockPi at a comfortable 3.4 Watts usage (when I don't switch on mining). Mind you that I attached a NVMe drive to it, for (among other things) blockchain storage. For pure staking a USB drive would suffice.
Your Pi needs to run a 64-bit OS to run the wallet, so 32-bit Raspbian release are not suitable. Then again: lots of 64-bit ARM Linux releases are available.
Happy staking!
