From the project

12-channel SiPM CSP + shaper + BLR + buffer board, built from the reworked single channel (../../../integration/single-channel/design/) as the single source of truth.

12-channel SiPM CSP + shaper + BLR + buffer board, built from the reworked single channel (../../../integration/single-channel/design/) as the single source of truth.

- Schematic = KiCad hierarchical: the single channel (minus board power entry) instantiated 12× as channel.kicadsch, plus a root twelve-channel.kicadsch with the 12 sheet instances + one common power section (power in + board-to-board daisy + up-rated reverse-polarity/PTC block + 470 µF bulk). Per-channel nets auto-scope to /chNN/. - PCB = tile-and-replicate: the routed single-channel channel row is cloned 12× (offset 25 mm in…
