• key layout generated using
• PCB design in KiCad
• uses with

Features:

• for Pro Micro or compatible controllers
• choc spacing (for choc v1 switches)
• pcb backplate with holes for rubber feet and threaded insert – allows usage on desks as well as tripod mounting the keyboard
• approximate size: 31 x 11 x 2 cm

repository file structure

• 
• pretty_pictures contains renders and images of the built keyboard
• dragonwings_backplate contains KiCAD files for the backplate as well as the gebers – the dagonwings_backplate_gerbers are tested but are missing a hole for the 5th rubber foot without which the board is not stable on a flat surface – the dragonwings_backplate_gerbers_updated are genreated from the updated kicad files and contain the additional hole for the 5th foot – these have not been tested but should work and one then would not have to drill the hole manually
• the dragonwings kicad files are contained in the root directory and the corresponding gerbers (tested and working) are in the dragonwings_gerbers directory, also available as a zip archive
• compiled firmware contains compiled firmware without or with first-up chord-send and tap-and-hold chord repeat – they contain two layers, one steno layer using GeminiPR and a qwerty steno layer which can be toggled with the lower key of the leftmost column
• firmware files to modify and compile yourself are available here (1up and repeat) and here (just QMK without steno extensions)
