// Kailh Choc PG1350 (v1) + Kailh Choc PG1353 (v2)
|
|
// This includes support for LOFREE low profile POM switches (Ghost, Phantom, Wizard)
|
|
//
|
|
// Nets
|
|
// from: corresponds to pin 1
|
|
// to: corresponds to pin 2
|
|
//
|
|
// Params
|
|
// reverse: default is false
|
|
// if true, will flip the footprint such that the pcb can be reversible
|
|
// side: default is B for Back
|
|
// the side on which to place the single-side footprint and designator
|
|
// hotswap: default is true
|
|
// if true, will include holes and pads for Kailh choc hotswap sockets
|
|
// solder: default is false
|
|
// if true, will include holes to solder switches (works with hotswap too)
|
|
// outer_pad_width_front: default 2.6
|
|
// outer_pad_width_back: default 2.6
|
|
// Allow you to make the outer hotswap pads smaller to silence DRC
|
|
// warnings when the sockets are to close to the edge cuts.
|
|
// show_keycaps: default is false
|
|
// if true, will add mx sized keycap box around the footprint (18mm)
|
|
// show_corner_marks: default is false
|
|
// if true, will add corner marks to indicate plate hole size and position
|
|
// include_stabilizer_pad: default is true
|
|
// if true, will add a corner pad for the stabilizer leg present in some
|
|
// Choc switches
|
|
// oval_stabilizer_pad: default is false
|
|
// if false, will add an oval pad for the stabilizer leg, and a round one
|
|
// if true. Note that the datasheet calls for a round one.
|
|
// choc_v1_support: default is false
|
|
// if true, will add lateral stabilizer holes that are required for
|
|
// Choc v1 footprints.
|
|
// keycaps_x: default is 18
|
|
// keycaps_y: default is 18
|
|
// Allows you to adjust the width of the keycap outline. For example,
|
|
// to show a 1.5u outline for easier aligning.
|
|
//
|
|
// notes:
|
|
// - hotswap and solder can be used together. The solder holes will then be
|
|
// - added above the hotswap holes.
|
|
//
|
|
// @infused-kim's improvements:
|
|
// - Added hotswap socket outlines
|
|
// - Moved switch corner marks from user layer to silk screen
|
|
// - Added option to adjust keycap size outlines (to show 1.5u outline)
|
|
// - Added option to add hotswap sockets and direct soldering holes at the
|
|
// same time
|
|
// - Made hotswap pads not overlap holes to fix DRC errors
|
|
// - Fixed DRC errors "Drilled holes co-located"
|
|
//
|
|
// @ceoloide's improvements:
|
|
// - Adjusted footprint to be Choc PG1353 (v2) compatible
|
|
// - Added option to hide corner marks, as they interfere with hotswap silkscreen
|
|
// - Added ability to specify board side
