Stratum is a 9‑key personal macropad with a rotary encoder, OLED display, and RGB backlighting under each key. It runs QMK firmware and supports five independent layers, allowing each key to perform unique functions depending on the active layer
I'm building a 9-key macropad with a rotary encoder and a small OLED screen, running on the Seeed XIAO RP2040. It's a mechanical keyboard setup where each key can be programmed to do something custom — shortcuts, launching apps, that kind of thing — and the knob is used for stuff like scrolling or volume, with the encoder browsing through different profiles I can see on the OLED.
