  9. Hardware
    10. 

  10. ========
    11. 

  11. 

  12. pyprofibus is able to run on any machine that supports Python. It also runs on embedded machines such as the `Raspberry Pi <https://en.wikipedia.org/wiki/Raspberry_Pi>`_ or even tiny microcontrollers such as the `ESP32 <https://en.wikipedia.org/wiki/ESP32>`_ (Micropython).

  19. Speed / Baud rate
    20. 

  20. =================
    21. 

  21. 

  22. The achievable Profibus-DP speed depends on the hardware that it runs on and what kind of serial transceiver is used. There is no software side artificial limit.
