Another clone of?? Matek which SpeedyBee cloned. They are now called CoreWing ?? How do you keep up.

yes, there are a lot of clones, that's why I don't panic when I see a board and it's not in the ardupilot list. We have a joke "there is wine in the bottles, there are no labels"

Those XT60 and XT90 need some heat.

you need a soldering iron of at least 60 watts, a regular copper one will also work

Maybe I could use SDR for Video Ground Station/VTR. That would be ideal for me.

Decoding 5GHz NTSC Video from Drones with a HackRF, DragonOS and SigDigger

Over on his YouTube channel Aaron has uploaded a video showing how we can SigDigger to decode analog NTSC video from a drone camera which is transmitted at 5.7 GHz. SigDigger is a rapidly evolving SDR program for Linux and MacOS that has a lot of built in functionality for inspecting signals in...

it seems good, but my hack rf one didn't have good video quality, but my antennas weren't matched through the analyzer. and the ones that came with the kit, I used the sdrangel package https://ports.freebsd.org/cgi/ports.cgi?query=sdrangel&stype=all&sektion=all

Today I finished a chassis for Two ESC and Flight Computer for my Rover. This brain box fits in the original controller location.
Mounted the flight computer on small tab. Found out Matek uses slightly different bolt hole pattern than the Sologood Wing.
I am using a UART GPS module but without SDA/SCL Compass. What am I missing without compass on ROVER?

I am still having trouble figuring out why you cannot drive R/C Signal Wire to ESC with ARM64 GPIO PWM pins.

Advanced Compass Setup — Copter documentation

ardupilot.org

It can work without a compass, so it isn't critical. However, having a compass is definitely better, especially for reliable heading and low-speed navigation. The ArduPilot documentation also mentions that while compass-less operation is possible in some cases, using a compass is recommended for Rover.

Thanks You I will order an M10 module today. I didn't realize it was so integral.

Had this smell of white smoke in my lab. Killed all house breakers and still smelled it.
Turns out my 3 Pack holder for 18650 had all the wires bare and was smouldering.
Looks like a wire on bottom joining poles must have grounded on something when I laid it down after work..
They are very cheaply made 18650 holders I bought. I was thinking the wires seemed mighty thin for 3 cells.

Kids don't let kids use LiPo indoors.

I mounted my flight controller at a weird angle because I want the "Heads Up Display" onscreen display to work without adjustments.

My Rovers previous controller bracket was at a 30 degree angle so I designed around that requirement. Flight controller mounted @30 degrees. So nap of earth should be correct.
