Questions
How big is the REG1-IpController2040 PCB?
It measures 83.2 × 15.7 mm and has 4 copper layers, 1 mm thick.
What parts does the REG1-IpController2040 use?
89 parts, built around the RP2040, TPS54202DDC, W25Q128JVSIQ and W5500. 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 REG1-IpController2040 KiCad files?
From the OpenKNX/OpenKNX-REG1 repository on GitHub, at the commit this page was made from: the board is hardware/EDA-Files/REG1-IpController2040/REG1-IpController2040.kicad_pcb and its schematic hardware/EDA-Files/NanoDCU/NanoDCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the REG1-IpController2040 design in my own project?
Its repository states no licence, so its author keeps all rights: ask OpenKNX before reusing the design.
