The Sortex QA90‑1303 Camera Board is a high‑resolution imaging module used in Bühler optical sorting systems to capture product images for defect detection and classification. Common failures on this board include burned or cracked surface‑mount components around the image sensor, degraded power regulator traces, and failure of the integrated camera interface IC (often due to overvoltage from the host controller). Initial diagnostics should verify that the board receives the correct 12 V/5 V supply rails, inspect for visible damage on the sensor area and surrounding circuitry, and check the I²C/SPI communication lines for proper voltage levels and error codes reported by the host PLC.[oss-gpt-20b]
