Questions
How big is the Cjh4858 gam3769 project PCB?
It measures 86.4 × 61 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cjh4858 gam3769 project use?
40 parts, built around the TM4C123GH6PMIR, LP2950-33LPRE3, MPU-6050 and ABM3-16.000MHZ-B2-T. 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 Cjh4858 gam3769 project KiCad files?
From the K0-p/Garfield-Wheel repository on GitHub, at the commit this page was made from: the board is hw/lab7811_project/cjh4858_gam3769_project.kicad_pcb and its schematic hw/baseline_project/ECE319KStarter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cjh4858 gam3769 project design in my own project?
Its repository states no licence, so its author keeps all rights: ask K0-p before reusing the design.
