Questions
How big is the Temperaturesensor+microcontrollerPCB PCB?
It measures 35 × 19.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Temperaturesensor+microcontrollerPCB use?
13 parts, built around the ATMEGA328P-AU. 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 Temperaturesensor+microcontrollerPCB KiCad files?
From the darshudarshans1122/PCB-Design-Portfolio repository on GitHub, at the commit this page was made from: the board is Temperature_Sensor_Microcontroller/Temperaturesensor+microcontrollerPCB.kicad_pcb and its schematic ESP32/ESP32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Temperaturesensor+microcontrollerPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask darshudarshans1122 before reusing the design.
