Questions
How big is the Light switch PCB?
It measures 101.6 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Light switch use?
142 parts, built around the STM32WB55CGU6, HLK-PM01, BTA12 and LFB182G45CGFD436. 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 Light switch KiCad files?
From the NguyenThanhHuy-debug/PCB_Real-Time-Power-Monitoring-System-Development-Light-Switch repository on GitHub, at the commit this page was made from: the board is Light switch.kicad_pcb and its schematic AC_Peripheral.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Light switch design in my own project?
Its repository states no licence, so its author keeps all rights: ask NguyenThanhHuy-debug before reusing the design.
