Questions
How big is the ECE477 PCB PCB?
It measures 65 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ECE477 PCB use?
103 parts, built around the FT230XQ-R, LSM6DS3, MPU-9250 and REG1117-3.3. 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 ECE477 PCB KiCad files?
From the michaellangford99/ECE47700 repository on GitHub, at the commit this page was made from: the board is pcb/ECE477_PCB/ECE477_PCB.kicad_pcb and its schematic pcb/ECE477_PCB/DataLogger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ECE477 PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask michaellangford99 before reusing the design.
