I am disassembling a drone for a project. I found this silver boxy component on a side circuit board that connects to the main circuit board on one side, and to the camera of the drone on the other side. It has a small black thing sticking out of it, so I don't know exactly what it is. Could anyone identify it?

Due to the antenna design, the system appears to be a LF RFiD system (125kHz or 134kHz).
- The chip you are searching the reference if a LF RFiD transceiver.
- The package is a SOIC-8.
Maybe your component is a MELEXIS MLX90109. The pinout seems to match. (antenna coil position).
The part with two pins and a black bead sticking out past the edge of the board looks to be a thermistor (temperature-sensitive resistor). You can disconnect it from the PCB and measure its nominal resistance at room temperature with a resistance meter. My guess is it'll probably be 10k (a very common value), but it could be just about anything. Then cover it with your fingers and see if the resistance goes up or down. If it goes up then it is a PTC (positive temperature coefficient) thermistor, and if it goes down it is an NTC (negative temperature coefficient) thermistor. I use a 10k NTC thermistor on a lot of products at work that looks nearly identical to this one (not that that says much) but it is a PR103J2 from US Sensor. If you're lucky maybe this is similar.
The black blob on the top side of the board is a COB and is probably an ASIC (application-specific integrated circuit) die covered up in goop. That will most likely be a custom part and will not be identifiable.

Five pin through hole. Middle three pins are for switch, outer pins are housing.
