Motors to ESC:
The four motors are connected directly to the ESC.
Power to ESC:
I connected an XT-60 male plug to power the ESC. Since my battery has an XT-90 connector, I used an XT-60 female to XT-90 male adapter.
Connections to Flight Controller:
GPS to FC
4V5 (SpeedyBee F405 V4) -> VCC (uBlox NEO-7M as GPS)
G (SpeedyBee F405 V4) -> GND (uBlox NEO-7M as GPS)
SDA (SpeedyBee F405 V4) -> SDA (uBlox NEO-7M as GPS)
SCL (SpeedyBee F405 V4) -> SCL (uBlox NEO-7M as GPS)
R6 (SpeedyBee F405 V4) -> TXD (uBlox NEO-7M as GPS)
T6 (SpeedyBee F405 V4) -> RXD (uBlox NEO-7M as GPS)
These are all the connections I have made on my drone.
Additional Notes:
I should note that before flashing ArduPilot, I had used iNav, which I have now removed. When I was using iNav, I didn’t encounter any issues with failsafe or the battery.
I think I might have made a mistake in what I mentioned earlier because the message ‘PreArm: Battery 1 low voltage failsafe’ appears when I don’t have the battery connected.
The issue is that it shows ‘PreArm: Logging failed’ (before I switch to arm) and ‘Arm: Logging failed’ (after I switch to arm), which prevents me from arming my drone. When I disable ARMING_CHECK, I can arm the drone and test the motors, but there is a slight delay.
For some reason when I go to the DataFlash Logs tab, in order to download the logs from the event, it says:
Getting list of log files…
No logs to download
I saw that in many cases you need a sd card in order to save the logs, but I inserted a sd card, after I formed it in FAT32, and still says no logs to download.
For what you said amilcarlucas I am trying it as I upload the post. To be honest with you, because Im new in drones and ardupilot in general, I didnt know that there was such a thing. I am going to give it a try and I will update you.
Im a bit stuck because I don’t know what vehicle template to select(and yes I saw that you say it doesnt need to fully match my vehicle). My main concern is that when I press the Create vehicle configuration from template, it says as a flight controller that it is the speedybee f405 mini v3(and it is locked so i cant change it) and I said in a previous post I have the speedybee f405 v4.
I’m worried because when I went (based on this Loading Firmware onto boards without existing ArduPilot firmware — Copter documentation, as i also said earlier) to do the “Download the ArduPilot firmware” step, it said “look for the directory with the name that most closely matches the autopilot”. There the only names that were closer to mine were the following:
SpeedyBeeF405Mini
SpeedyBeeF405Mini-heli
SpeedyBeeF405WING
SpeedyBeeF405WING-heli
And therefore since Im working with a quadcopter, I chose the SpeedyBeeF405Mini.
Have I done something wrong?
Also not to make a second post, what can I do about my problem with logs and logging failed, do you have any idea, since I can’t download logs, since the drone won’t arm?
I tried to change these parameters and IT WORKED, I was able to arm my drone.
Here are the values that I had in these specific parameters before I changed them:
I still don’t have any logs to download, but as you can see in the screenshot, the PreArm and Arm: Logging failed messages disappeared. I should also note that my sd card is 16gb. I saw, and correct me if im wrong, that it is better to have a smaller storage sd card(4,8 gb).
Last im going to finish the steps for. the Ardupilot methodic configurator.
Thanks again in advance and thanks also for the fix.
This is only correct for a board that doesn’t have an Sd card. The default parameters should have been right if the firmware matched the board. But hey it’s a SpeedyBee. Or more appropriate on the forum a NeedyBee
So the problem is that the firmware that is flashed in the board, which for the speedybee mini, isn’t matching with the board that I have, which is the speedybee f405 v4?
And if so, what do you think is the best solution in my problem? Should I erase the data from the chip and flash it again?
I’m asking because I don’t want to do a short term fix and then after a while I get the same thing again or something else related to it.
Also how can I not have any logs to download, even though I armed the drone?
Finally, I have a general question, not related to any of these. Which would you say is a good, not so expensive, flight controller? Because I thought this speedybee board was good, but you got me thinking with the NeedyBee comment.
I’ll also give the nod of approval to Matek. I’ve used many of their boards (F4 and H7) and they’ve worked well. I haven’t used the Kakute boards, but I’ve used enough other Holybro products that I’d take @dkemxr’s word for it.
Yes, smaller cards are better, but trying to find a good quality card under 16gb or 8gb isn’t worth the struggle. You don’t need a fancy, high speed card. Pretty much any good quality will do the job.
