Questions
How big is the STARBIE CARRIER YETI JARVIS PCB?
It measures 48 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the STARBIE CARRIER YETI JARVIS use?
14 parts, built around the DHT11 and XIAO ESP32C3. 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 STARBIE CARRIER YETI JARVIS KiCad files?
From the rafay-069/starbie- repository on GitHub, at the commit this page was made from: the board is hardware/STARBIE_CARRIER_YETI_JARVIS.kicad_pcb and its schematic hardware/STARBIE_CARRIER_YETI_JARVIS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STARBIE CARRIER YETI JARVIS design in my own project?
Its repository states no licence, so its author keeps all rights: ask rafay-069 before reusing the design.
