From the project
HybridImager: open hybrid single-pixel, event, frame, and spectral scientific imaging research workspace
This is the first board-level HybridImager sensor draft. It deliberately uses a sparse multi-site single-pixel detector array instead of one central bucket only. The geometry follows a Weiqi-like 7x7 conceptual grid with 21 populated detector sites.
- Validate detector spacing and sparse reconstruction geometry. - Provide per-site signal pads for external TIA/comparator experiments. - Reserve board area for three TIA banks, one timestamp MCU/FPGA, sync SMA connectors, power/sync header, and a 2x20 expansion header. - Keep V1 buildable and inspectable before committing to dense custom sensor…
