Kit Content

The Reviung 39 is a compact 39-key (37.5%) column-staggered keyboard driven by a Pro Micro. This is the Mk-II revision, which uses hotswap sockets (no soldering your switches in permanently) and the larger, more heat-tolerant WS2812B RGB LEDs for underglow and a single accent LED.

Which version is this?

This guide covers the Reviung 39 Mk-II, the version we stock. It differs from the original Reviung 39 (which used the smaller SK6812MINI LEDs) and from the Reviung 39S (a "simple" through-hole variant with hand-soldered switches). The Mk-II builds almost identically to the Reviung 41.
