Hello @dakhnod
1. My question is: Is there any firmware that accomplishes the same thing, but is Arduino-based?
No, there is no firmware based on Arduino.
2. I have a lot of boards based on esp32 or rp2040, but they do not seem supported by the firmware you provide....
you could port NFC COCKPIT VCOM to tesp32 or rp2040, soure code can be downloaded from NFC Cockpit | NXP Semiconductors
