• Add Softserial support to F7

[Pairan]

does this include the ones from Matek?

Support for F411 CPU

[digitalentity]

@Pairan it doesn't include the board support by itself, but it should be possible to add F411-based targets from Matek after this is merged.

okay :) ... this would open up for smaller wings to carry a reliable fc like the minis from Matek

@Pairan Matek F411 is now PR'ed and will be on 2.0. See #3146

Nice .... closing the gap :)

Target check
Airbot just released this board in the past few weeks.

I contacted Airbot support about an appropriate iNav target. They stated that BF Omnibus F4fw (Firework) works with this board. I’ve tried the firework v2 target in iNav but received “connection time out. The board failed to respond in 10 seconds” I’ve tried every other Omnibus F4 target. Each has its own problem usually pwm 4 has no output. Tried looking in rcgroups.com Any links or different targets I should try?
