KiCAD PCB design for a V-USB breakout board
This breadboard compatible board has all the components required for a V-USB based project, suitable for connecting directly to the pins of an Atmel.
Features include:
- Voltage limiting Zener diodes on D+ and D- so the Atmel can be run anywhere between 3.3 and 5 V
- Ability to be powered from USB (if jumper is set) and/or external power (via Vin pin). Schottky diodes prevent back-power in both cases.
- USB ID pin is broken out
NOTE: If running the Atmel at 5V, the board will draw about 20 mA from either D+ or D- when they are driven high.

Questions
How big is the VUSBHeader PCB?
It measures 16.6 × 20.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VUSBHeader use?
12 parts. 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 VUSBHeader KiCad files?
From the JPEWdev/vusb-breakout repository on GitHub, at the commit this page was made from: the board is VUSBHeader.kicad_pcb and its schematic VUSBHeader.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VUSBHeader design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
