Questions
How big is the Scale bridge PCB?
It measures 68 × 32 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Scale bridge use?
37 parts, built around the LP5907MFX-4.5. 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 Scale bridge KiCad files?
From the atuleu/aristeus repository on GitHub, at the commit this page was made from: the board is devices/scale_bridge/scale_bridge.kicad_pcb and its schematic devices/BLE_environmental-sensor/BLE_environmental-sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Scale bridge design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
