How to connect YU01 to VIA?

Try online VIA: https://via.evove.top/ or https://usevia.app/
​

1. Please use the right V3 .JSON file for the YU01 without needing to toggle V2 definitions. Here is the link: YU01.json
2. Load V3 JSON File: Load the corresponding V3 JSON file for your VIA keyboard. Ensure that the “Use V2 definitions” option is turned off when loading the V3 JSON file. You may need to load 2-3 times to let your keyboard be detected.

If you cannot find the load button, make sure you have opened the Design tab as shown below.
