Balthazar open-hardware laptop - IO USB module
Open-hardware laptop computer modules description and concept.
These are electronic schematic modules as presented at https://balthazar.space/wiki/Balthazar with the main aim for team access. See the main repository for other designs.
BalthazarIO module is a simple USB2.0 four-port hub for the internal devices: keyboard and touchpad, webcam and optional audiocard. Additional simplification and pcb size reduction was done recently.
