N42a7c: common questions

What microcontroller does the N42a7c use?

The N42a7c is built around the XIAO-nRF52840-SMD, from the Nordic nRF family.

How big is the N42a7c PCB?

The N42a7c measures 265.5 × 105.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the N42a7c?

107 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the N42a7c design files?

From the hatanoh/n40a8-pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the N42a7c design in my own project?

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

Can I test firmware for the N42a7c 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.
