Compatible with most TKL boards like F1-8X, Jane ME, Jane V3 etc. FOR 8K PCB - PLEASE WRAP A TISSUE AROUND YOUR TWEEZERS TO TEST - testing with bare tweezers will actuate more than 1 key because of how sensitive it is. once switches are installed, it will work fine and not actuate more than 1 key. Specifications: Connection Options Removable onboard top facing USB-C Standard/Alternate JST support with daughterboard Note: All PCBs come with JST footprint, but some do not have the JST port soldered.
