Questions
How big is the Comm Module Project PCB?
It measures 32.4 × 38.1 mm and has 4 copper layers, 1.63 mm thick.
What parts does the Comm Module Project use?
21 parts, built around the ESP32-C3-MINI-1-N4, AZ1117CH-3.3TRG1, T50201500000G and TS04-66-70-BK-160-SMT. 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 Comm Module Project KiCad files?
From the polrolnik2/Smart-Home-Modular repository on GitHub, at the commit this page was made from: the board is Modules/Comm_Module/Comm_Module_Project/Comm_Module_Project.kicad_pcb and its schematic Modules/230V_Motor_Module/230V_Motor_Project/230V_Motor_Project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Comm Module Project design in my own project?
Its repository states no licence, so its author keeps all rights: ask polrolnik2 before reusing the design.
