Overview
SpeedMacro is an open-source printed circuit board by KipJM, from the KipJM/speedmacro-lite repository on GitHub, published under the BSD-3-Clause licence. It is a 2-layer board of 63.5 × 115 mm with 40 parts on 41 nets, routed with 488 tracks and 52 vias.
It is built around the SK6812MINI-E. Its parts include 25 diodes, 1 IC, 1 connector and 1 switch. It belongs with the keyboards and input boards of this library.
Main components

README.mdspeedmacro-lite
A small macropad with a similar key layout to the Davinci Resolve speed editor.
Includes a rotary encoder (no click) and an OLED screen.
The key layout is designed to mimic a combination of the left and middle part of a Davinci Resolve speed editor, with two 1.5u "in" "out" point buttons at the top and a long 3u "play/pause" button at the bottom, with stabilizers. ergobleds are included with each key, plus a row of additional lighting is added at the top.
CAD Model
Schematics
This macro pad uses a matrix wiring model, however caution that the electrical arrangement of switches do not match the actual physical location of the switches, because of the 2-3-3-1 switch layout this board uses.
Firmware
SpeedMacro lite uses QMK firmware, but feel free to use other firmware platforms. A minimal sample firmware build is provided.

Questions
How big is the SpeedMacro PCB?
It measures 63.5 × 115 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SpeedMacro use?
40 parts, built around the SK6812MINI-E. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SpeedMacro KiCad files?
From the KipJM/speedmacro-lite repository on GitHub, at the commit this page was made from: the board is PCB/SpeedMacro/SpeedMacro.kicad_pcb and its schematic PCB/SpeedMacro/SpeedMacro.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SpeedMacro design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
