Assemble: common questions

What microcontroller does the Assemble use?

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

How big is the Assemble PCB?

The Assemble measures 269.2 × 100.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Assemble?

110 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Assemble design files?

From the derui/ThingnusBall repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Assemble design in my own project?

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

Can I test firmware for the Assemble 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.
