carlozepeda-SJSU/Arduino-with-temperature-sensor
Designed and built a custom environmental monitoring system using an Arduino Uno R4 to track temperature, humidity, pressure, and power data in real time.
It measures 30 × 50 mm and has 2 copper layers, 1.6 mm thick.
23 parts, built around the DC-005. 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 alexgvg/FAN-PCB repository on GitHub, at the commit this page was made from: the board is fanpcb/fanpcb.kicad_pcb and its schematic fanpcb/fan.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 alexgvg before reusing the design.
