Questions
How big is the Weight sensor pcb PCB?
It measures 95.5 × 68.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Weight sensor pcb use?
90 parts, built around the STM32F042F4P6, SN65HVD230DR, INA333AIDGKR and 54602-908LF. 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 Weight sensor pcb KiCad files?
From the Capstone-Group-C1/weight-sensor-pcb repository on GitHub, at the commit this page was made from: the board is weight-sensor-pcb/weight-sensor-pcb.kicad_pcb and its schematic weight-sensor-pcb/can_interface.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Weight sensor pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Capstone-Group-C1 before reusing the design.
