A project log for Aloidia: wireless split solar powered keyboard

Aloidia is a staggered, split, fully wireless solar-powered mechanical keyboard with extremely long battery life.

Currently, the memory displays can give information about connection status as well as battery level. I've chosen an icon as the battery level but it is also possible to have the percentage displayed. A very slight issue with the current setup is that the LDO powering the display discharges itself very slowly when its enable pin is low (TPS7A0333DBVR). The next iteration will use the P-version of that same LDO (TPS7A0333PDBVR) which has active discharge when disabled.
