Questions
How big is the Iris led v2 PCB?
It measures 26.6 × 14.9 mm and has 2 copper layers, 1.58 mm thick.
What parts does the Iris led v2 use?
28 parts, built around the TPS61169DCK, AO3401A, RC0603FR-7W2R2L and CL21A225KBQNNNE. 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 Iris led v2 KiCad files?
From the bunnie/iris-hw repository on GitHub, at the commit this page was made from: the board is imager-tool/elec/iris_led_v2/iris_led_v2.kicad_pcb and its schematic imager-tool/elec/iris_led_v2/iris_led_v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Iris led v2 design in my own project?
Its repository publishes it under the CERN-OHL-S-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).
