Questions
How big is the LEDRacer V01 PCB?
It measures 252 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LEDRacer V01 use?
48 parts, built around the 54601-908WPLF and TN0104N3-G. 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 LEDRacer V01 KiCad files?
From the ENTS-Source/formula-diode repository on GitHub, at the commit this page was made from: the board is boards/kicad/LEDRacer_V01.kicad_pcb and its schematic boards/kicad/Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LEDRacer V01 design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
