Edge io ring fusion: common questions

What microcontroller does the Edge io ring fusion use?

The Edge io ring fusion is built around the nRF52840, from the Nordic nRF family.

How big is the Edge io ring fusion PCB?

The Edge io ring fusion measures 40 × 18 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Edge io ring fusion?

6 components, from 6 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 Edge io ring fusion design files?

From the gunnchOS3k/gunnchos-hardware-industrial-design repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Edge io ring fusion design in my own project?

Yes, under the terms of its MIT license, which gunnchOS3k chose for the repository.

Can I test firmware for the Edge io ring fusion 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.
