EOL of Flash memory
The M25P32-VMF6P flash memory on the conv-ttl-blo appears to be EOL. A
few stocks might still be available for urgent production, but ideally
it should be replaced.
If a similar footprint flash can be found it would be ideal, with a new version of the board to be released (v5) for the new component.
Better still, a design that can take multiple flash chip footprints might be required, and could be the most future-proof solution.
