Questions
How big is the Project233 PCB?
It measures 93 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Project233 use?
63 parts, built around the STM32F103C8T6, MAX30102EFD+T, AMS1117-1.8 and RT9193-33GB. 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 Project233 KiCad files?
From the tuanthanhhh/project233 repository on GitHub, at the commit this page was made from: the board is PCB_Kicad/PCB/project233/project233.kicad_pcb and its schematic PCB_Kicad/PCB/project233/MCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Project233 design in my own project?
Its repository states no licence, so its author keeps all rights: ask tuanthanhhh before reusing the design.
