title_body: How do I wire up this transmitter and camera
upvoted_answer: These components can be split into two functional groups, one for transmitting a picture and one for receiving it, which aren't connected to one another by wires. The Runcam camera and Eachine VTX are both parts of the transmitting section, while the receiver doesn't need to be soldered to anything else in the receiving part.
  Required Soldered Connections:
  You'll need to make the following wire connections between the different components: (splicing together the components' connector pigtails is recommended as opposed to trying to solder directly to the camera)
  
  Battery+ → VTX 7-24V wire
  Battery- → VTX GND wire (there are a total of two available, choose either one)
  Battery+ or VTX +5V wire → Runcam 5-36V wire
  Battery- or VTX GND wire → Runcam GND wire (in 5-pin camera connector, not the 2-pin camera controller connector)
  Runcam Video wire → VTX VIDEO wire
  
  Essentially, both the camera and VTX need to be connected to each other for the analog video signal (one wire) and each need to have connections to ground/GND and a positive voltage source within their requirements.
  Battery Setup:
  In this setup, the VTX is actually the component that constrains the kind of power sources/batteries you can use. It requires 7-24V to operate, which means you can use 2S-5S LiPo batteries with it. (or another battery pack within the same voltage range)
  Most drone/RC LiPo batteries these days come with either an XT30 or XT60 connector, but can be purchased with other terminations. See this page for a list of the most common ones. Once you know what your battery's connector is called, you can purchase a set of connectors online and solder them to the VTX and camera as required.
  It's unlikely you'll be able to match the connectors that come with the parts together. While the connectors are all off-the-shelf parts, their usage is unfortunately not really that standardized between manufacturers. You're probably better off just cutting the cable that came with the camera in half and soldering it together with the pigtail wires that come with the VTX.
  Once this is done, you can hopefully power on the VTX, camera, and receiver without issues, (remember to screw on the VTX's antenna before powering up so you don't damage it!!!) set the VTX and receiver to the same channel, and view the picture on the connected Android phone/tablet.
  Did I leave something out? Please let me know if I did and something doesn't make sense...
