Depending on when you got your Hubsan X4 H107C you may have a low resolution camera (480P). Newer models include a 2 megapixel HD 720P camera and you can upgrade your existing quad to have the same camera. This project requires some soldering.
Here’s what you’ll need:
Here is what you’ll need (wire cutters not shown)
Flip the quad over to reveal two tiny screws securing the two halves of the quad body. Unscrew the two screws using the #0 Phillips head screwdriver.
Release the bottom from each leg near the motor by bending the leg slightly until the bottom separates as shown here.
Lift the bottom away from the rest of the quad. The camera is on the right inside the bottom half of the quad body. It is connected to the main printed circuit board with two wires. The black wire is negative (ground) and the red wire is positive power.
Here’s where the camera module wires connect to the main printed circuit board. The black wire needs to be removed by heating the existing solder and gently pulling the wire with needle nose pliers. The red wire is a little different. The red wire shares a terminal with another wire used elsewhere. To avoid any issue with the second wire, I cut the existing camera module red wire. The new camera module red wire will use an existing open positive terminal shown here. I verified with a volt meter that the terminal was the same voltage as the existing connection before deciding to take that approach.
I used a third-hand tool to help hold the quad while I did the detailed soldering work.
Use the #0 Phillips head screw driver to remove the four tiny screws from the inside of the bottom half of the quad body. Remove the battery holder to reveal the camera circuit board. Gently take the camera circuit board out of the body shell noting that the lens is friction fitted into the body shell. Set the old camera aside.
Now it’s time to reverse the process steps with the new camera. I elected to swap out the old black bottom with a shiny new red one just for looks. Install the camera by removing the protective plastic tab off of the lens and insert the lens into the bottom body shell. Note that the camera switch needs to be exposed (lower right hand corner) through the body shell so you can start and stop recording. The camera needs no screws. Insert the battery holder into the body shell lens end first. The battery holder has a small structure that must align with the camera. Use four tiny screws with your #0 Phillips head screwdriver to secure the battery holder to the body. I found I needed to apply a small amount of pressure on the battery holder to get the holes to line up for the screws. Tin the ends of the new camera wires by heating the ends and applying a small amount of solder on them. Solder the black wire to the same terminal on the main circuit board used by the old camera. Solder the red wire to the open terminal on the main circuit board by heating the wire and pushing it through the hole by using the needle nose pliers. You may need to apply a small amount of additional solder on this joint.
Reinstall the bottom half of the body by aligning the two screw posts with those on the top half. There is an inset allowing one to fit inside the other for a perfect alignment. Note the camera end of the body to ensure that part is seated correctly. Reinstall the two screws. Bend each leg to restore the body and leg connections. Now you’re ready to record in HD.
