Questions
How big is the Web controlled relay board v2.0 PCB?
It measures 165.2 × 114.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Web controlled relay board v2.0 use?
71 parts, built around the HLK-20M05, HLK-PM03 and G3MB-202PL. 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 Web controlled relay board v2.0 KiCad files?
From the ambadran/Free-Lance-Projects repository on GitHub, at the commit this page was made from: the board is web_controlled_relay_board_v2.0/Electronics/Electronics.kicad_pcb and its schematic distress_call_robot/Circuit/Circuit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Web controlled relay board v2.0 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ambadran before reusing the design.
