Dear all,
I am used to A64-OLinuXino (https://www.olimex.com/Products/OLinuXino/A64/A64-OLinuXino/open-source-hardware), but for setting up a small home server with more RAM I am considering the iMX8MP-SOM-4GB-IND (https://www.olimex.com/Products/SOM/NXP-iMX8/iMX8MP-SOM-4GB-IND/open-source-hardware) + iMX8MP-SOM-EVB-IND (https://www.olimex.com/Products/SOM/NXP-iMX8/iMX8MP-SOM-EVB-IND/open-source-hardware) combo.
What I miss from the A64-OLinuXino is the LiPo battery connector, that has proven to be very useful and effective against power cuts.
So a new product idea would be an external board that acts as a UPS for the 5V power. Optionally, this board could have an UEXT connector for informing the main board on the status of the battery (%, charging status...). Ideally, the LiPo battery would be discharged during power cuts and recharged when the power is back.
It would be a board with the following connectors: 5V inlet (barrel plug socket), 5V outlet (either a short cable ending with a barrel plug or a block terminal), LiPo battery connection, and, optionally, an UEXT connector for communicating to the computer the status of the battery.
