Questions
How big is the GSLeaf PCB?
It measures 30 × 103 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GSLeaf use?
116 parts, built around the CC1101RGP, CS42L52-CNZ, MMA8452QT and IRLML6401. 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 GSLeaf KiCad files?
From the Kreyl/LocketRadioSnd repository on GitHub, at the commit this page was made from: the board is PCB/GSLeaf.kicad_pcb and its schematic PCB/GSLeaf.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GSLeaf design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
