Questions
How big is the Monitoring Gunung PCB?
It measures 61.3 × 63.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Monitoring Gunung use?
50 parts, built around the CH340C, ESP32-WROOM-32E, ATGM336H-5N31 and BME280. 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 Monitoring Gunung KiCad files?
From the rafdi03/PCB_Desain repository on GitHub, at the commit this page was made from: the board is Hikerslink_V1/Monitoring_Gunung.kicad_pcb and its schematic Hikerslink_V1/Monitoring_Gunung.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Monitoring Gunung design in my own project?
Its repository states no licence, so its author keeps all rights: ask rafdi03 before reusing the design.
