Wearable v2 nrf: common questions

What microcontroller does the Wearable v2 nrf use?

The Wearable v2 nrf is built around the NRF52811-QCXX, from the Nordic nRF family.

How big is the Wearable v2 nrf PCB?

The Wearable v2 nrf measures 40.3 × 40 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Wearable v2 nrf?

60 components, from 44 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 Wearable v2 nrf design files?

From the ray4477/Senior-design-fit-ml 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 Wearable v2 nrf design in my own project?

Yes, under the terms of its MIT license, which ray4477 chose for the repository.

Can I test firmware for the Wearable v2 nrf 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.
