NRF52811 USB: common questions

What microcontroller does the NRF52811 USB use?

The NRF52811 USB is built around the NRF52811-QFAA, from the Nordic nRF family.

How big is the NRF52811 USB PCB?

The NRF52811 USB measures 41.8 × 14.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the NRF52811 USB?

42 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the NRF52811 USB design files?

From the alvarop/chaac repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the NRF52811 USB design in my own project?

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

Can I test firmware for the NRF52811 USB 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.
