    Version 3 of the eBUS adapter fulfils the arbitration times required by the eBUS specification for the first time.

    This is made possible by the use of a PIC which, among other things, brings the following advantages:

    • minimal time delay due to hardware-related programming
    • flexible, configurable variants for connecting to the host:
      • USB serial via CP2102 (onboard)
      • Raspberry Pi via GPIO/ttyAMA0
      • WIFI via LOLIN/Wemos D1 mini with ESP-8266
      • Ethernet via USR-ES1 module with W5500
    • full support for ebusd enhanced protocol version 1 and standard protocol
    • updatable firmware using a serial bootloader

    In order to be able to get all these options on a 5cm x 5cm board, almost only SMD is used:
