Questions
How big is the BTL ESD PCB?
It measures 73.5 × 92.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BTL ESD use?
152 parts, built around the CH340C, INA128UA, TPS54331D and AMS1117-3.3. 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 BTL ESD KiCad files?
From the DONGKHOA/SMART_LED_CONTROL repository on GitHub, at the commit this page was made from: the board is Hardware/BTL_ESD/BTL_ESD.kicad_pcb and its schematic Hardware/BTL_ESD/BTL_ESD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BTL ESD design in my own project?
Its repository states no licence, so its author keeps all rights: ask DONGKHOA before reusing the design.
