 "symptom": "This note reported that the XIAO's OV3660 answers its PID but lacks the hardware compression block, and recommended falling back to RGB565 plus software JPEG on the S3 CPU. That is wrong. The part compresses on-sensor: measured QVGA 36015.50 us, VGA 36017.67, SVGA 36032.83, UXGA 71936.50, all with zero NULL frames, and QXGA JPEG at 467663 bytes.",
