Welcome to my PCB projects repository! This space is dedicated to documenting my journey in designing, creating, and improving printed circuit boards (PCBs).
It measures 88 × 70 mm and has 4 copper layers, 1.77 mm thick.
199 parts, built around the RP2040, ADL5611ARKZ-R7, AD8314ARMZ and PAT1220-C-3DB-T5. 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.
From the GReX-Telescope/FrontendModule repository on GitHub, at the commit this page was made from: the board is hardware/GreX Frontend.kicad_pcb and its schematic hardware/GreX Frontend.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask GReX-Telescope before reusing the design.
