"we plan an upgrade to the PCB design in order to [...] reduce the final production cost. So far, we come up with three changes: 1) removal of the costly Sata3 Marvell controller, 2) removal of the SIM card slot, and 3) removal of the second NAND rom. In particular, leaving out the Sata3 controller was initially criticized by some of the contributing volunteers, but we demonstrated that existing M.2 connectors could easily replace its functionality using cheap M.2 to Sata3 adapters." https://www.powerpc-notebook.org/2024/04/spring-restart/
