Questions
How big is the Osprey68 PCB?
It measures 150 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Osprey68 use?
51 parts, built around the ATMEGA16A-PU, 74HC245D, SN74LVC126APWR-TP and 74HC74D. 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 Osprey68 KiCad files?
From the clementtttttttt/osprey_dev repository on GitHub, at the commit this page was made from: the board is kicad/osprey68.kicad_pcb and its schematic kicad/logicshift.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Osprey68 design in my own project?
Its repository states no licence, so its author keeps all rights: ask clementtttttttt before reusing the design.
