Hey @awrelll ... @phonikg is your EthEmbedded guy.
Yeah - the SBCs "work", but they aren't great. Rpi Model A in particular can only barely keep up with the blockchain. Without copying the blockchain data onto a Rpi Model A, you could be waiting months to sync. Rpi2 is much better, but still a long way from a Desktop.
Roll on Light Client :-)
Anything I can do to help?
Yes please - contact me at LG@Fuzo.com as I'd like to work with other embedded systems people that are ETH enthusiasts to build a standard solution that will work in a range of ETHEmbedded scenarios including the orchestration of devices via your Smartphone - with a HW token used for Trust and IDentity
