I don't recall running into that issue when I flashed my H743 board. I'll have to try it loading it again via Betaflgith and full chip erase to see what happens.

I was not able to install it at all with iNav. Tried many different things including turning off chip erase. It just never worked. I had to use the STM32 uploader, link is on the first post of the thread.

Betaflight 10.7.0 Configurator w/Full Chip Erase enabled: Erased and flashed firmware no issues. INav 2.5.0 with Full Chip Erase: Froze up half way through the Erase progress cycle. INav 2.5.0 w/o Full Chip Erase: Froze up about 2/3rds the way through the Erase progress cycle. Perhaps the version of Betaflight might make a difference on why I was able to do a full chip erase and firmware load, or, maybe my board and/or PC are playing nicely together??? Either way, it's good to know the alternative solution. I'll update my post on how to flash the firmware. |

Now that I have firmware loaded, I ran into another problem. The new canbus GPS made specially for this controller does not come with the proper cable to connect the M8Q-CAN to the H743. Both cables that it come with will not fit. I don't have the ability to make cables with these tiny connections. So I pugged in a readymade RC 220 GPS that comes with the proper cable in the box. It works great.

I don't recall if the CAN cable was in the FC bag or the M8Q-CAN bag...probably the later. |

so, now here my take at the CAN bus, the part which was missing in the earlier video on thr Matek H743:

How is everyone's experience with SLCAN mode in MissionPlanner. It rarely connects. Any tips and tricks?

Never had an issue with mine...when I was using it to update my M8Q-CAN GPS that is. I just clicked on the SLCan Mode CAN1 button and it displayed my attached CAN device.

Ok today I was able to conduct range tests with the H743 and Dragonlink 433mhz system. It seems Matek is using the same voltage regulation system on this as they did with previous boards. Results were very similar to the F765 board. First test is with the flight controller powered only with a usb cable. This powers up the board but not the voltage regulators. This is to establish the baseline that includes any noise from the flight board CPU. In this test I was able to go out 45' from the Dragonlink (TX is sitting on a fence). Next I removed the USB cable and plugged in the flight board to a 6s Battery. This powers up the 5V and 9/12V regulators. For this test the main 5V servo regulator was not connected so we are only seeing the impact of the 9/12V regulator. Just powered on my the micro power test range drops to 30'. This would be enough for some very long range flights. The next test was the loaded test. With the regulator configured for 9V, I plugged in a Matek 1.2GHZ VTX and Runcam2 to the flight board. In this test the range was reduced to just 4' from the transmitter. It seems that the higher the load on the 9/12v regulators the more noise it puts out in the 433mhz range. The outcome is if you want to use this flight board for long range flying, you should use an external regulator for 9 or 12v systems on your plane.

So, I suppose one of the other versions (i.e. slim, mini) would be the way to go and run tried and true BEC/regulators. Thanks for the testing.
