About the Unwired PCB

Unwired is an open source Nordic nRF PCB design by NoxAevi, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 29.4 × 61.1 mm, with 83 components from 46 distinct parts.

Its main chip is the QFN-48-1EP_6x6mm_P0.4mm_EP4.2x4.2mm, from the Nordic nRF family. Other key parts include the TUSB320, TPD6S300A and TVS2200DRV. By type, the board carries 30 capacitors, 27 resistors, 8 ICs, 6 inductors, 4 connectors and 3 diodes.

It belongs with the iot & wireless designs in this gallery.

From the project

Man, don't you just hate how so many devices are wired instead of wireless? Well, I sure do.

Man, don't you just hate how so many devices are wired instead of wireless? Well, I sure do.

Unwired is a project that aims to take a USB peripheral (like a mouse/keyboard) and allow you to connect to it wirelessly while simultaniously being as compact as possible because wired stuff can be pretty annoying at times

The KiCad project lives in the NoxAevi/Unwired repository on GitHub; these links point at the commit this page was built from.

Unwired: common questions

What microcontroller does the Unwired use?

The Unwired is built around the QFN-48-1EP_6x6mm_P0.4mm_EP4.2x4.2mm, from the Nordic nRF family.

How big is the Unwired PCB?

The Unwired measures 29.4 × 61.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Unwired?

83 components, from 46 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 Unwired design files?

From the NoxAevi/Unwired 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 Unwired design in my own project?

Yes, under the terms of its GPL-3.0 license, which NoxAevi chose for the repository.

Can I test firmware for the Unwired 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.
