Help with hardware selection - ground application

Help / Getting Started
1

hello folks! 1st time post here…

i’m building a crawl-space inspection rover and i’m very interested in OpenHD, particularly after a Walsnail/CADDX VTX literally caught on fire while bench testing, even though it was being cooled by a fan

however, i’m pretty lost regarding hardware selection for an OpenHD system

my situation…

  • if it matters for firmware flashing, etc., i run only Linux
  • short range, color, good quality HD video transmission (1080 is sufficient)
  • field monitor is a Lilliput A7S 7" Full HD Monitor (16:10 aspect ratio)
  • latency is less of an issue - sub 250 ms should be fine
  • low light environment (artificial lighting will be employed)
  • i’d like to be able to record still images - if possible, then recording video is optional
  • control (both Tx and Rx) is provided by a RadioMaster Boxer (2.4 GHz, ELRS)

i’d like to keep the setup as simple as possible while still providing great color video quality - all i need at this point is advice for the hardware/software for video transmission/receiving (SBCs, camera, etc.)

All of this is very much possible, but I’d recommend joining our Telegram or Discord channel, since there you’ll get a lot more input.
For your setup, I’d use a Raspberry Pi Zero2w for the air, a imx708 or imx462(better in low light enviroments) and a simple Pi3 or 4 on the ground.

Latency and Heat is not that bad, so you can even run without a fan, although I’d recommend a fand for higher power wifi-cards.

There I usually recommend the Asus AC56, but you can also use a Tplink T4u plus which is easier to get
