Loongcat40: A 4x10 Gasket-Mounted OLED Keyboard

The loongcat40 is the culmination of five years of keyboard design. Powered by a Raspberry Pi Pico (RP2040), this 40% mechanical keyboard features a large 2.08" SH1122 OLED display, a custom 3D-printed gasket-mounted case, and QMK firmware support. It is a fully open-source project exploring the intersection of ergonomics and digital aesthetics.
