Pre cpl coordinate fix v1
Pre cpl coordinate fix v1 is an open source AVR/Arduino PCB design by mehrantsi: a 6-layer, 300 × 248.8 mm board with 520 components (103 distinct parts). It is built around the C7421276, SN74AHCT14PWR, SN74AHCT157PWR, SN74AHCT08DR and more. Filed under displays & leds.
An 8-bit computer. Successor to MSAP-1
This directory is the manufacturing target for the full-SMD, six-layer MSAP-2 rev.C board. It is separate from the unrouted, module-grouped rev.A development exports.
The production generator is fail-closed: source-only output is clearly labeled, and prototype Gerbers are generated only after the routed board passes KiCad with zero DRC violations and zero unconnected items. The resulting assembly bundle is explicitly PROTOTYPE material. When its release metrics record firstArticleOrder.inputsReady: true, it may be uploaded only after explicit user approval as an unqualified two-board first…
