TEST-XIAO-nRF5240: common questions

What microcontroller does the TEST-XIAO-nRF5240 use?

The TEST-XIAO-nRF5240 is built around the XIAO-nRF52840-SMD, from the Nordic nRF family.

How big is the TEST-XIAO-nRF5240 PCB?

The TEST-XIAO-nRF5240 measures 25.4 × 31.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TEST-XIAO-nRF5240?

6 components, from 5 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the TEST-XIAO-nRF5240 design files?

From the 74th/74th-oshw-projects repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the TEST-XIAO-nRF5240 design in my own project?

Yes, under the terms of its MIT license, which 74th chose for the repository.

Can I test firmware for the TEST-XIAO-nRF5240 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.
