Hey longhathuc - no, the OAK-FFC-4P cannot support four OAK-FFC-48MP modules. Each module requires a 4-lane MIPI port, and the board has only two: CAM_A and CAM_D.
You can use up to two modules. On this RVC2 board, each module supports up to 5312 × 6000 (about 32 MP) at 10 FPS. The 32 MP mode still requires four MIPI lanes.
Best regards,
Oskar
