I have read this article which describes the prototype of Ethkrem, a development board for IOT and Ethereum: https://devpost.com/software/elkrem-development-board-for-iot-ethereum .
However, it is not clear to me that this platform installs an Ethereum light client (Geth or Parity) on their micro-controller? Or they install Ethereum client on a routing connected to this micro-controller? like this example: https://www.youtube.com/watch?v=4BrvGnuGteI ?
Is it possible to install an Ethereum light client on
Nano Pi using EthArmbian? (https://docs.armbian.com/#supported-boards)
Note: EthArmbian is a custom Linux image for ARM SoC devices that runs Geth or Parity Ethereum clients as a boot service and automatically turns your ARM SoC into an full Ethereum node. (https://github.com/diglos/userpatches#etharmbian)
