Questions
How big is the RS485 antenna switch v1.2 PCB?
It measures 193.5 × 95 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RS485 antenna switch v1.2 use?
90 parts, built around the SN74LVC2G34DBV, DS18B20, L7805 and ULN2803A. 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 RS485 antenna switch v1.2 KiCad files?
From the EI9SP/Remote-Antenna-Switch repository on GitHub, at the commit this page was made from: the board is Hardware/KiCad/RS485_antenna_switch_v1.2.kicad_pcb and its schematic Hardware/KiCad/RS485_antenna_switch_v1.2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RS485 antenna switch v1.2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask EI9SP before reusing the design.
