RoyalBlue54L-Feather: common questions

What microcontroller does the RoyalBlue54L-Feather use?

The RoyalBlue54L-Feather is built around the BM15x, from the Nordic nRF family.

How big is the RoyalBlue54L-Feather PCB?

The RoyalBlue54L-Feather measures 58.4 × 22.9 mm, has 8 copper layers and is 1.6 mm thick.

How many components are on the RoyalBlue54L-Feather?

48 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the RoyalBlue54L-Feather design files?

From the LordsBoards/RoyalBlue54L-Feather-Hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the RoyalBlue54L-Feather design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which LordsBoards chose for the repository.

Can I test firmware for the RoyalBlue54L-Feather without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
