Questions
How big is the Exjobb PCB?
It measures 98 × 55.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Exjobb use?
84 parts, built around the OPA859QDSGRQ1, OPA2677IDDA, LMG1210RVRR and TOMCT16031002ZT1. 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 Exjobb KiCad files?
From the Daavsan/Exjobb repository on GitHub, at the commit this page was made from: the board is KiCad/V1/V1.kicad_pcb and its schematic Davids KiCad/MosTest_GanFet/MosTest_GanFet.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Exjobb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Daavsan before reusing the design.
