Drone Electronic Component Appraisal

Drone Camera-Input + Wifi Transmission PCB

This item is a compact, red-colored Printed Circuit Board (PCB) designed for integration into small electronic devices, likely drones, given its described function. It measures approximately 3-4 cm in length and width, indicating its miniature form factor. The PCB is constructed from a red fiberglass substrate, commonly used in electronics due to its insulation properties and durability. Numerous surface-mount components populate the board, including resistors (e.g., R1, R2, R3, R8, RC9), capacitors (e.g., C1, C2, C3, C4, C5, C6, C7, C8, C11, C12, C16), and integrated circuits (ICs). Key distinguishing features include a large multi-pin flex cable connector at the top, which appears to be a Zero Insertion Force (ZIF) or similar type, indicating a connection point for a ribbon cable, likely from a camera module or another main board. Several prominent ICs are visible: one labeled 'MK 25040BTIG 2410' and another larger one marked 'K1900 ENFF9A D2413' (likely a microcontroller or a video processing unit). Another small IC is labeled 'U2 LW5930 BCA40', which could be a voltage regulator or a specific video component. A crystal oscillator, clearly marked '40.000 MHZ', is present, essential for clocking digital circuits. The board exhibits a neat layout with clear solder pads and traces. There are several through-hole pads labeled, indicating various power or data lines such as '3V3' (3.3V power), 'GND' (Ground), 'PA8', 'TM', 'E1', 'TC', 'T', and 'EN'. The overall condition appears excellent with no visible damage, wear, or repair marks; all solder joints appear clean and intact, suggesting a new or well-maintained component. The manufacturing details, specifically the '2410' and 'D2413' markings on the ICs, likely represent date codes (e.g., 2024, 10th week), placing its estimated age as relatively recent. The high density of components in such a small form factor, combined with the context of 'Wifi Transmission of live camera feed', points to advanced miniaturization and integration, characteristic of modern drone technology.
