Wasn't sure where to post this, but I figured Long Range FPV was a safe bet as that's what 99% of Ardupilot builds are used for. 

I just discovered that the Flywoo F745 boards (Flywoo Goku F745 16x16 FC, Flywoo Goku Hex F745 16x16 FC, Flywoo Goku HD 745 Evo 40A AIO 20x20, Flywoo Goku GN 745 40A AIO 25.5x25.5) support Ardupilot! The target has been added to the main build: https://ardupilot.org/plane/docs/common-...-f745.html

This really opens up some possibilities for advanced semi-autonomous micro quads and small wings! It has a much steeper learning curve than BF or iNav, but is much more powerful and robust. I'm adding an Arduplane micro wing to my project list for the summer

Due to the chip shortage, most of the Flywoo F745 boards are now shipping with the STM32F745VE (512k flash) MCU in place of the STM32F745VG MCU (1M flash). No problem for Betaflight/iNav/Emuflight, but unfortunately it makes these boards a non-starter for Ardupilot due to the flash memory limitation. 

That said, if anyone has a F745 Nano (16x16) FC with a VG chip, I'd be interested in buying! Please PM me. 

   

That's not great especially since it was a really good AIO FC for ArduPilot.

Its hard to trust the online listings at most sites with regards to details on the STM chips onboard the FC's. Unless someone has bought one and knows which vendor has the STM32F745VG MCU board in stock.

You may want to post this request in the Buy/Sell/Trade section.

I will have to look at the FC on The Ninja...it was purchased before the shortage and it may have the older chipset.

I reached out to Flywoo about this because they are the perfect boards for micro builds using Ardupilot. They were aware of the issue and planned on resuming using chips with >=1M flash as soon as they could secure a supply. They also seemed open to creating a line of Ardupilot-compatible FCs. If you'd be interested in that, please email them and let them know there is demand!

I have a Flywoo Goku F745HD EVO AIO,(bought from RaceDayQuads) and I believe it is the 512k version.

Fine with me, as I don't use Ardu Pilot, But thought I would post this in case any one else is looking to use the boards for Ardu Pilot you will probably want to wait until they get the other chips.

FYI, these are in stock at flywoo. A bit pricy though. 

It must the the price they have to pay to source that MCU specifically required for Ardupilot.

Ardu guys build big expensive toys not like us FPV Crash Pilots

I'm about to convert my Flywoo Explorer from iNav to Ardupilot. Anyone have a settings backup file they'd like to share, or any specific setting adjustments they found necessary?

Thanks!

Random post..

Are the 16x16 getting better publicity now? I think there has been some concern of the size alone just not being heavy duty enough. I would compare it from a sub compact to a full size. I would feel more secure in a Cadillac than a Miata.

I'm still torn on the AIO boards, but Emax left a really bad taste in my mouth. I think I would prefer a stack, for both ease, and cost, of replacement, and i would think less heat transfer?

Troll...off

I forgot to update this thread, but I discovered that all of my boards with the F745VE MCU (512kb flash per datasheet) actually report 1Mb flash in STM32CubeProgammer, and can be successfully flashed with Ardupilot.

I don't know whether the VE chips are just VG chips that didn't pass QC, or of the datasheet is wrong or what, but I've flashed a few boards now and run into no issues. YMMV.

Another option I recently found for a 16x16 Ardu-capable stack is the JHEMCU GF16. I haven't seen them at any US retailers yet, but they're available from China for about $50. They also make a 3g 1-2s F405 AIO with ELRS that I created an Ardupilot target for. I haven't had time to complete my build, but someone has already made a micro indoor Arducopter (51mm props) with it.

Does anyone know what the PC0 pad is for on these boards?  Is it simply a spare with PDB trace to the PC0 pin on the F7 chip?  Thoughts?

Sorry, a bit off the thread topic, but same FC, so seemed like a good place to ask

This is great!   I just successfully flashed the Flywoo745Nano on a F745VE with zero errors.  Currently sitting in Mission Planner with it fully connected and responding.
