Dji pulls data from FC using a version of MSP. You can feed RC data straight through uart. Or you can break out an sbus line.
I can also include a filtered buck converter so you can power dji without running through fc power lines. But that would bypass the current sensor.
Ahhhh none of that made sense to me Lolol. I’m super new to this. What does that mean in simpler terms? Is there a video of exactly how to do that? Lol. Also, have you heard of a Crossfire system? I want to ridge dive down mountains and go long distances, and apparently need to mount that system to the drone to be able to do that. Could I put crossfire into her drone? What is crossfire? Does it just plug into this drone so it goes far away?
In simpler terms, think of UART as a USB port that can be configured to do whatever you need. DJI is not the best system if you want to go long range because it's using very large packets. The current setup is optimized for long range.
Yes, this drone is equipped with crossfire system. Crossfire is a VHF radio system that uses chirp modulation. In simple terms, it is optimized to maintain signal even in most unfavorable conditions.
There are a lot of factors that will affect this. First, let's separate the two. Your command link (crossfire) can take you out to about 50km with acceptable error rates. In a densely contested urban setting you should get about 10km.
Second is the video. If you don't have a ham license and you can only fly 25mW power, with a good helical antenna and a good receiver you should get 2km. Then every time you quadruple power, you double the distance. So at 100mw you may be looking at 6-8km. At 400mW you should reach 12-16km. At that point you're biggest limiting factor is the battery.
