Questions
How big is the UP1-GW UART PCB?
It measures 39 × 39 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UP1-GW UART use?
67 parts, built around the RP2040, LTV-217-B-G, TPS7A4901DGN and USBLC6-2SC6. 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 UP1-GW UART KiCad files?
From the OpenKNX/OpenKNX-UP1 repository on GitHub, at the commit this page was made from: the board is hardware/EDA-Files/UP1-GW-UART/UP1-GW-UART.kicad_pcb and its schematic hardware/EDA-Files/UP1-Controller2040/UP1-Controller2040.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UP1-GW UART design in my own project?
Its repository states no licence, so its author keeps all rights: ask OpenKNX before reusing the design.
