Got 2 camera systems in. One is a 600 tvl, with the camera, tx combo, runs of a 3.3v lipo, or up to 5v.
2nd one is a 1200 tvl, that requires a seperate tx. Higher voltage op range.
Little time I had them working on the bench, they got pretty warm.
Going to try and mount camera on nose with a little fan to help move some air across the board, and run wire feed to rear car. Will run off a 3s lipo I use for rock crawler.
Wish I could get my hands on a dummy or non working loco for cheap.
Play with this setup until chip shortage catches back up and the digital stuff becomes available.
I'll post what I come up with.
