I designed one a while back and used esp32 with custom firmware I wrote. Completely wireless and worked fine. A few years later I made a new board and used zmk with a couple of nrf52480 which works great! The esp32s were a bit heavy in the current draw and I wanted to try out low profile switches. All boards I made were fully split and had hot swap.
