    7. 7 - TX isolated.
    8. 8 - PTT1 out (max 50V/400mA).
    9. 9 - CW1 out (max 50V/400mA).
    10. 10 - FSK out (max 50V/400mA).
    11. 11 - MIC input.
    12. 12 - TX audio.
    13. 13 - RX audio.
    14. 14 - Ground.

    19. 19 - RX isolated.
    20. 20 - PTT2 out (max 50V/400mA).
    21. 21 - CW2 out (max 50V/400mA).
    22. 22 - reserved out (max 50V/400mA).
    23. 23 - Foot sw input.
    24. 24 - TX audio GND.
    25. 25 - RX audio GND.
  • PA PTT - Cinch PA PTT output (max 50V/400mA).
  • USB PC - isolated USB connect to PC.
  • FOOT SWITCH - Cinch foot switch input.
  • PADDLE - 6.3 mm stereo jack CW paddle input.
  • 12V DC - Arduino DC power only - not use.
  • KEYBOARD - USB A female connector for USB keyboard (with Arduino Mega-ADK only)
  • ARDUINO USB - non isolated USB for Arduino firmware upload only.
  • DTR/RTS - DTR/RTS outputs ON/OFF - because the specifications of winkey defines default as ON, you need to have the ability to disable the outputs.
