Questions
How big is the Digikeytraning PCB?
It measures 47.5 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Digikeytraning use?
15 parts, built around the BS-7 and EG1218. 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 Digikeytraning KiCad files?
From the Gregification/cse-labs repository on GitHub, at the commit this page was made from: the board is homelab/kicad/digikeytraning/digikeytraning.kicad_pcb and its schematic homelab/kicad/IS37SML01G1/IS37SML01G1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Digikeytraning design in my own project?
Its repository states no licence, so its author keeps all rights: ask Gregification before reusing the design.
