Questions
How big is the IR PCB PCB?
It measures 49.6 × 49 mm and has 4 copper layers, 1.6 mm thick.
What parts does the IR PCB use?
128 parts, built around the GD32E103CBT6, SI2301, TSOP4856 and M28S. 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 IR PCB KiCad files?
From the Kreyl/IR_PCB repository on GitHub, at the commit this page was made from: the board is IR_PCB_hw/IR_PCB.kicad_pcb and its schematic IR_PCB_hw/IR_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IR PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
