All sounds great until you jump into the price game and the real usability of the SBC you are thinking of using to add intelligence to your washing machine, fridge, or your home’s doorlock. Cost need to be next to nothing (who want to spend more?), usability must be plug and play, including buffered IO, WiFi-BT connections that really work (you are not thinking to wire your home right?) and a battery charger-manager for black out situations. Once implemented, your product needs to work 24/7. Probably you have tried a few small SBCs that you found on the market, and understood that they freeze and do not work after a few hours. It is a problem! This happens because those easy and cheap objects, have not been designed to industrial standards like we have done within our U1-U5 line of product.
