Questions
How big is the DC2026 LASIR PCB?
It measures 50.8 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DC2026 LASIR use?
38 parts, built around the ATTINY1616-SN and TSOP38238. 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 DC2026 LASIR KiCad files?
From the CmdrZin/chips_avr_examples repository on GitHub, at the commit this page was made from: the board is NewAVR/DC2026_LASIR/KiCad/DC2026_LASIR/DC2026_LASIR.kicad_pcb and its schematic NewAVR/DC2026_LASIR/KiCad/DC2026_LASIR/DC2026_LASIR.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DC2026 LASIR 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).
