pi40 Keyboard Kit

From: $25.00

SKU: KK1U0011 Categories: , ,


The pi40 mechanical keyboard kit is a full solder DIY board powered by a Raspberry Pi Pico controller with support for per-key RGB, a 0.91″ OLED display, and one EC11 style rotary encoder. The ortholinear layout is inspired by the OLKB Planck and Planck EZ, and offers a fully functional keyboard condensed into a 40% form factor. This layout is a4 × 12 grid with a 2-unit-wide spacebar on the bottom row. A 2u stabilizer is highly recommended.

Thanks to the addition of Raspberry Pi Pico support in QMK and VIA, we can offer a project that uses the most popular keyboard firmwares, making it super easy to change your keymap and rotary encoder functions!

The OLED screen is used to display your active layer, classic indicators for Caps, Scroll and Num lock, as well as which RGB mode your keyboard is on.
