Questions

How big is the BL54L15μ DevKit PCB?

It measures 25.4 × 43.2 mm and has 4 copper layers, 1.54 mm thick.

What parts does the BL54L15μ DevKit use?

45 parts, built around the NPM1304-QEAA-R. 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 BL54L15μ DevKit KiCad files?

From the danstiner/embedded repository on GitHub, at the commit this page was made from: the board is HW/BL54L15μ_DevKit/BL54L15μ_DevKit.kicad_pcb and its schematic HW/BL54L15μ_DevKit/BL54L15μ_DevKit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the BL54L15μ DevKit design in my own project?

Its repository states no licence, so its author keeps all rights: ask danstiner before reusing the design.
