Any support for STM32F1?

Not yet, but there's some significant work already done. There's a thin hardware abstraction layer in place and the ESP32 implementation is built on top of that layer, but the STM32 implementation is not yet functional.

With this done, not sure if already considered or something tthat could be considered, is support for R9 gear?

Expected that some features may not be possible (i.e. over-the-air updates) but it would be a great way to give that gear some good use.

The base work of listing hardware and pin mapping already exists from other similar projects.

Thanks
