README
README.mdBikeLite
This is the schematic and PCB for a buck converter and 555 timer to add flashing LEDs to my bike.
The output voltage is 5.2V, (theoretically) capable of up to 2A
(5.2V is the combined forward voltage of a white and red LED in series)
The PCB contains connections for two switches: 1) enable and 2) flash disable

Questions
How big is the BikeLite PCB?
It measures 51.8 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BikeLite use?
23 parts, built around the LM2576HVT-ADJ, NE555P and FQP30N06. 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 BikeLite KiCad files?
From the francesmatthew/BikeLite repository on GitHub, at the commit this page was made from: the board is BikeLite.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BikeLite design in my own project?
Its repository states no licence, so its author keeps all rights: ask francesmatthew before reusing the design.
