Eachine TX03

I needed a new small AIO style camera to just stick on some small models when I wanted to fly them FPV. So I went looking for what was current, and I found the Eachine TX03. An AIO camera and vtx. I would probably use this on something like my Flite Test Mighty Mini Tiny Trainer, or other models that size, and I am sure I can couple this up with a small single cell LiPo battery to make a decent short range backpack FPV unit. So, on to the features






Eachine TX03 Features

  • 1/3 CMOS Sensor
  • M7 10mm lens
  • 120° HFOV, 150°DFOV
  • 600 TVL resolution, NTSC
  • LED display
  • 9 Bands, 72 channels, including Raceband (not all channels are legal in all areas)1
  • 25mW, 50mW, 200mW output
  • RHCP clover leaf style antenna, non removable.
  • 1S LiPo power required (3.7V - 4.2V)

Eachine TX03 Initial Thoughts

First thought is that it looks pretty solid, and it is light. That combination makes for decent crash survivability, assuming nothing else lands on it. it looks like it can be modified to allow the use of an external OSD, such as a MinimOSD, or connected to an AIO flight controller with a built in OSD. I did a similar mod on the AIO camera/vtx on my Tiny Whoop, and while it is nice to have on larger aircraft that fly further, the 'need' for an OSD on something that small is questionable. I think this AIO is going to be used on my Flight Test Mighty Mini Tiny Trainer (they need to come up with shorter names), I just need to figure how to power it. Do i just add a small 1S LiPo, or do I add a voltage regulator to step the 3S main battery down to 1S level.

Check back in a few days2 for an update


  • 1. Check you local regulations, may need a amateur radio license. Some of the channels appear in more than one band
  • 2. Hopefully :)
