Mitsubishi ESPHome CN105 Microcontroller - PAC-USWHS002-WF-1 plug compatible
Sep 02,2025
Compatibility NoteThis version is plug compatible with the PAC-USWHS002-WF-1 and allows direct swap using the existing wiring. The WF-2 uses a smaller connector which would require an adapter cable to use with this project - instead click HERE for the WF-2 compatible module. Please ensure you have a WF-1 module if you plan on using this version of the board (the WF-1 has one (1) connector, the WF-2 has two (2) connectors). For more information on how to determine which version you have check ou...
