How To Flash ESCs With Arduino Nano 

Thanks JC, your tutorials are always so easy to understand and follow. Your videos are still making an impact to this day. R.I.P bro.

Know this is old , but still reference this every now and then ! Thanks for this !

hey Jc, I just wanted to say thank you for all the great content you put out. With alot of help from your videos I finished my first build yesterday and nothing fried. Anyway thank you man, I really appreciate your dedication to sharing your knowledge of the hobby.

Dude thank you. I’m just starting to learn about all this. I’m gettin pretty good with airplanes and I’m gonna custom build my own quad copter.

Great video, as usual...! Thanks, and keep doing that fine work! You're showing me things I wouldn't think of at my current level of understanding! I feel like I'm enrolled in JC's school of Everything Quad...

It works the exact same way on the Arduino Uno. The chip may look different, but it is just a different model of the same chip with the same internal layout but made for SMD use instead of being placed on a socket. The only thing that might be different is the USB to UART chip used on the board, as most cloned Arduinos use a different (and cheaper?) one.

i have HAKRC_32bit 35A, but the chip is AT32F421K8U7, is there posible to flash it to am32?

Man, I have 2 sets of ESC does not show up in BLheli suit when I do this. They were fine until I tried to flash them to latest BLheli firmware. If you want, I can send them to you and you can make a tutorial how to fix them and you can keep them. One is Littlebee otherone is RTF black mini 30A.

Hi, I think what you have explained is very clear, thank you! I am still at the stage of figuring out how to flash a bootloader onto a board. Do you have any content on that or can refer me to content on that? Thank you!

Always wondered about this. As long as I've been into quads there has always been passthrough. Oh and first.

Thanks it really helped i just wanted yo know which digital pin goes to signal wire worked flawlessly didn't have to mess with beta flight passtrough

Funny - I did this just yesterday. You can also power the ESC directly from the Arduino (at least that was enough for the ESCs I was flashing)

I bought an arduino Nano just to set the ESC, the program says: Found no valid ESC Configuration

I've had some cheap blheli esc's, but the program can't connect to them. It won't find the esc's at all. Please help. The esc's are called: readytosky 40a 2-6s opto. I found it out already. When you're using a arduino uno, you have to connect your esc's to pin 8-11.

Thank you !

Thankyou very much Your video help me can connect to esc again after it can't passthrough by fc 👍

Great! Keep it up!

Where do you get those plain power distribution boards? All the ones I can find have voltage regulators on them.

Maybe this is a dumb question, but which ESCs can be programmed through the connector and which require a chip clip? Can _all_ ESCs be programmed through the connector via an Arduino?? That would be stunning.

Hey JC. I wanted to ask you something about the Omnibus FC. I have the F3 version and I cannot seem to power the FC using the VBAT pin (3rd row). The FC does power on and respond when it's connected to the 5V of the USB. I don't think the voltage regulator is fried as I checked the continuity between the GND and output & input. When checking the voltage between the input and GND of the regulator, when 15V is connected to the VBAT, I get no reading (0V). i hope this makes sense and that you can reply. Sorry I posted it two times both here and in the Discussions tab :)

can i do this directly to the battery without pdb right=??

Nice tutorial. Can i flash Furibee BLheli S 30 amp ESC Thanks

My STRIX ESC says it is BLHeli S. Can I use this same procedure with the BLHeli S download I did for my ESCs. Or is this only for BLHeli 32? BTW I only do fixed wing and do not have any Flight Controllers unless the FT AURA 5 Lite is considered a FC. All of the YT videos so far only seem to deal with programming QUAD or FIGHTING BOTS. No one addresses programming BLHeli for fixed wing a/c.

why would u flash thru the arduino? just curious and new too the scene, cant u flash with blheli

Do you know if I can use my USBASP boards to update BLHeli_32? I use these boards to update/program other ATmega based boards.

@Project Blue Facon: Using the same connection method you can also flash a new Blheli32 version, right?

@ Project Blue Falcon : Perfect , used USB FDTI on mini pro ATmega328 ,,,used your Nano wiring and Ardiuno nano firmware..and it connects just fine with the Skystar fine Bhelis 40A. Is it possible to program more then one esc with arduino at the same time ?. ?

Hi, which escs are you using?

can you flash blheli esc firmware version​s too? for example if I wanted to run dshot on an esc that doesn't have the right firmware originally? nevermind I see that the aduino acts as a mock flight controller so you can do the same things with it in blheli suit as you can with a FC.

Hey man, thanks for the video! I am going to buy BLHeli ESC's and I would like to program them. I already have an Arduino Uno. What parameters can I change and what do they exactly mean, I couldn't find anything regarding what the settings mean. Where can I find that? Also, do I need a programming card, or is the BlHeliSuite the same, yet slightly more advanced?

you mentioned bugs in the new betaflight. how many of those bugs affect flight?

hello jc. can i use this method flashing fairy firware esc into blheli firmware. tnx

Thanks for the video, how to do it with 4in1 escs?

i thought blheli and betaflight would take care of that. seems like their updates are making flying harder. hmm

Hello! Great video. I am interested in this, my daughter and I are building a underwater rov with 6 motors and six escs. we want to flash reverse compatibility. do you think this is possible? FVT LITTLEBEE BLheli-s are the escs we got.

Still have contents to learn of. RIP buddy!

hey JC, I have a question. I have some little b 20a blheli s. escs. I was on 14.6. when I flashed to 14.9. all but the #4 esc took the flash. when I tried to flash #4. it told me that the esc was erased or unknown. now it won't take any flash. it shows up as the letter U when I connect. what can I do.

How can I get that program ?

Great! Thanks

Hello uploader, Could U pls show us a BLheli firmware flashing for helicopter brushless tail conversion. Or just tell us the procedure at least. Thanks genius.

wow!! are you reading mij mind? i wanted to ask this.

Rest in Peace
