Questions
How big is the BLESEN PCB?
It measures 37.6 × 25 mm and has 4 copper layers, 1.58 mm thick.
What parts does the BLESEN use?
43 parts, built around the DLF162500LT-5028A1, SHTC3 and B3U-1000P. 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 BLESEN KiCad files?
From the Exeu/BLESEN repository on GitHub, at the commit this page was made from: the board is BLESEN.kicad_pcb and its schematic BLESEN-backups/BLESEN-2024-07-12_213619/BLESEN.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BLESEN design in my own project?
Its repository states no licence, so its author keeps all rights: ask Exeu before reusing the design.
