Sidewalk Devkit: common questions
What microcontroller does the Sidewalk Devkit use?
The Sidewalk Devkit is built around the nRF54L15-QFAA, from the Nordic nRF family.
How big is the Sidewalk Devkit PCB?
The Sidewalk Devkit measures 55 × 34 mm, has 6 copper layers and is 1.687 mm thick.
How many components are on the Sidewalk Devkit?
137 components, from 67 distinct parts. The full bill of materials is listed on this page.
Where can I download the Sidewalk Devkit design files?
From the hlord2000/Sidewalk_Devkit repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Sidewalk Devkit design in my own project?
Yes, under the terms of its CERN-OHL-P-2.0 license, which hlord2000 chose for the repository.
Can I test firmware for the Sidewalk Devkit 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.
