Juho T. (aka Squalius-cephalus), designer of the popular Silakka54, shared his Haili58 – wireless, supports MX and Gateron low-profile switches, designed to be used with a USB dongle.

It’s like silakka54, but better! […] The main improvements include the removal of the TRRS connection, which significantly reduces the risk of accidentally damaging the MCU. Support for low-profile switches has also been added, whereas the silakka54 only supports MX switches – Squalius-cephalus.
