SPARC, the PCB That Tries to Avoid Starting Over

Field notes

The proposed workflow separates a persistent baseboard from smaller replaceable cards, so a team could change selected capabilities without discarding the whole platform. The visible hardware work centers on an interposer, with connectors facing a main logic board that remains in development. SPITA reports partial silicon checks using overclocked I2C and SPI, but identifies integrated system validation, wider interface coverage, and customer benefits as work still to be established.
