Questions
How big is the Modbus simple pcb PCB?
It measures 200 × 63 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Modbus simple pcb use?
63 parts, built around the ADS1115, KH-2.54FH-1X15P-H8.5 and MJ-179PH. 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 Modbus simple pcb KiCad files?
From the KikuchiMakoto/modbus_simple_pcb repository on GitHub, at the commit this page was made from: the board is modbus_simple_pcb.kicad_pcb and its schematic modbus_simple_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Modbus simple pcb 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).
