ArduCopter on a Goku GN405 Nano

Any thoughts on being able to install on this FC? It’s a bit muddled because they have apparently changed chips numerous times over the past year. This is a Flywoo Explorer LR v2.2 which I have upgraded the GPS to a GPS/compass module.

On mine, it comes up in Betaflight as target: Matek F411. The printing on the chip is F415OG6, which from ST’s site says it has 1MB flash. I know it will be limited due to flash size, but I essentially just want angle or horizon mode, and altitude and position/gps hold and a proper RTH.

I’m currently running Inav (beta firmware from Flywoo) on it but as I’m planning on all future builds being ArduCopter I’d love to get it on here.

Thanks!

Were you ever able to install Ardupilot on this? I just got another Explorer and it now has yet another version: GH405 Nano. Wondering if I even want to attempt installing Ardupilot on it.
