more fpv and miniKwad related stuff

I’m in the fpv community for something over 10 years now. I’ve seen MultiWii, baseflight, cleanflight, betaflight, emuFlight, QuickSilver, OpenPilot/LibrePilot, INAV and used and still use every single firmware. I've also seen many manufacturers and transmission protocols like Spektrum, FlySky, FrSky, IRC Ghost, ExpressLRS. And I also flashed and configured my ESCs with SimonK or BLHELI firmware.

So I also did contribute to betaflight with the GPS preset (which worked fine in testing) and I've updated a target. https://github.com/km-coded/firmware-presets - merged into official https://github.com/km-coded/unified-targets - merged into official

Maybe not the latest and greatest way to write ESC firmware or configure an ESC, but there was a time when you had to connect your ESC to your computer and start the corresponding configuration Software like KKMultikopter Flashtool and/or BLHELI https://github.com/km-coded/ArduinoESCusbLinker

As ExpressLRS started looking around for some readymade tx/rx, the manufacturer ImmersionRC brought their GHOST system. IRC GHOST is a very closed source firmware, where you can brick your rx and only reflash it to have ExpressLRS working - it's a good brick! But I found a way to download the firmware binaries from their server and hope someone will finally find a way to write them into GHOST hardware to have it back as before https://github.com/km-coded/IRC_ghost_firmware

Speaking of ExpressLRS: best radio link with the best community i came across - I mean, it's the community with the most active developers and most changes in everything. Like: most frequencies (from 433 MHz up to 2.4 GHz), many redundant systems (retransmit on more frequencies), long range system with selectable packet rate, extended telemetry... And as said before, the was IRC GHOST, their transmitters had an OLED screen, someone did a good job at adding ONE of the two available transmitters OLED screens - i did the rest and added OLED to ttgo_v1 & ttgo_v2 and any other following esp32 based transmitter. Today there's so many transmitters with OLED screen and icons and the possibility to set everything in the module itself https://github.com/km-coded/ExpressLRS_OLED - merged into official
