Questions
How big is the STM PLC Dev PCB?
It measures 154.1 × 141 mm and has 4 copper layers, 1.6 mm thick.
What parts does the STM PLC Dev use?
121 parts, built around the LM3489MM, MOC3021M, TPD2EUSB30DRT and P6KE30CA. 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 STM PLC Dev KiCad files?
From the samiul000/PCB repository on GitHub, at the commit this page was made from: the board is STM32_PLC_Dev_Board/STM_PLC_Dev.kicad_pcb and its schematic ATTiny_board/ATTiny_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM PLC Dev design in my own project?
Its repository publishes it under the LGPL-2.1 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
