NEWS: Eachine DTX3, switchable power 5.8G VTx with builtin DVR

It’s not an AIO FPV camera but a switchable power 5.8G VTX including a builtin DVR and up to 72CH: http://www.banggood.com/Eachine-DTX03-DVR-5_8G-72CH-025mW50mW200mW-Switchable-VTX-w-Audio-NTSCPAL-p-1141123.html. You select either 25mW, 50mW or 200mW. Works fine from 1s up to +5V but you will need a BEC/Vreg from 2S systems. Definitively, I hope the DVR part will be superior to their former 4-in-1 module where when recording was turned on, the FPV connexion became so laggy…. Impossible to fly FPV in such conditions. It seems to be since I can recognize the three button of a HMDVR module. 7g standalone… so you will have to add two extra gram for the FPV cam. Clearly more adapted from 120mm brushless machine.

    Low band?
    Legal to use those frequency?

  • Ben says:

    There is the usual 2 wires (black and red interlaced) to give the power to the camera/transmitter. Still badly named on the manuel and Banggood photo (red wire is called “ground”, as on the TX03 description/manual, but of course red wire is “positive” and not ground).

    What are the other 3 wires (red/black/yellow) => I guess it is audio/ ground/video, but is it an input or a local output ???
    It’s no described anywher …
