The Stront – name derived from strontium in Polish, not from the Dutch meaning – is an open-source split keyboard by Evgenii Vilkov aka zzeneg.

Really happy to present my latest keyboard. It has a layout heavily adapted for my fingers, but I hope they are not so unique. Also my first time using Cirque trackpad and LCD display with a help of quantum painter and lvgl, it was very fun to work with them! – zzeneg.

Evgenii is a prolific creator with designs like the Smol, PicaChoc, or recently v2.1 of the Pica40.

His latest model, the Stront, is a low-pro split keyboard with 38 keys, only compatible with Choc v1 for now, featuring Waveshare RP2040 Zero MCUs, an LCD on one side and Cirque trackpad on the other.
