Questions
How big is the Rtk mini PCB?
It measures 35 × 40 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Rtk mini use?
75 parts, built around the ZED-F9P-04B, OPA344PA, ESD7104MUTAG and LM66100DCK. 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 Rtk mini KiCad files?
From the Poppy-Robotics/rtk repository on GitHub, at the commit this page was made from: the board is rtk-mini/rtk-mini.kicad_pcb and its schematic mcu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rtk mini design in my own project?
Its repository states no licence, so its author keeps all rights: ask Poppy-Robotics before reusing the design.
