Doing so removes confusion over which is which albeit at the compromise of a second user accessible slot. microSD has become quite cheap and a microSD socket will add less than US$1 to the BOM cost. The PCB footprint even including mounted card isn't much greater than a 56 pin TSSOP flash part yet provides the trivial upgrade/replacement option as above. -john -- john.cooper_at_third-harmonic.comReceived on 2009-04-10 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
