* Mariano ([marianomd](https://github.com/marianomd)), continued Kuba's work and made it up to useable condition! Added gimbals, buttons, AFHDS2A, PPM, CRSF.
* Kuba ([qba667](https://github.com/qba667)), started this work and made this project possible, it is forked from his repo.
* Wilhelm ([wimalopaan](https://github.com/wimalopaan)) added 16 channels SBUS16 / IBUS16 modes.
* Rafael ([rafolg](https://github.com/rafolg)), ported FlySky Hall Gimbal support from EdgeTX.
* Tom ([tmcadam](https://github.com/tmcadam)) fixed AFHDS2A PWM mode selection.
* The internal RF code was taken from the great KotelloRC's [erfly6: Er9X for i6 and i6x](https://bitbucket.org/KotelloRC/erfly6/src/master/).
* Some of the internal RF fixes are a result of analysing [pascallanger's](https://github.com/pascallanger) [DIY-Multiprotocol-TX-Module](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module).
* ExpressLRS configurator is based on elrsV2/V3.lua from [ExpressLRS](https://github.com/ExpressLRS/ExpressLRS).
* Some of the ports are from [EdgeTX](https://github.com/EdgeTX/edgetx/).
