Questions
How big is the PCB FINAL UPDATED PCB?
It measures 70 × 70.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PCB FINAL UPDATED use?
111 parts, built around the INA188ID, BD6220F-E2, LMC7660IMX and OP07. 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 PCB FINAL UPDATED KiCad files?
From the bash227/ECG-Motor-Control-Power-Management-PCB repository on GitHub, at the commit this page was made from: the board is Hardware/PCB_FINAL_UPDATED.kicad_pcb and its schematic Hardware/ANALOG CIRCUIT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB FINAL UPDATED design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
