About the Hyper Wheel XIAO PCB

Hyper Wheel XIAO is an open source Nordic nRF PCB design by AnotherBuildCorner, published on GitHub. It is a 2-layer board measuring 103.5 × 68 mm, with 26 components from 16 distinct parts.

Its main chip is the Seeed Studio XIAO nRF52840, from the Nordic nRF family. Other key parts include the CSD85301Q2 and BQ29700DSER. By type, the board carries 6 ICs, 3 connectors, 1 jumper and 1 switch.

It belongs with the displays & leds, power & battery and keyboards designs in this gallery.

From the project

A programmable HID control interface that replaces discrete key presses with continuous rotary input, enabling precise, context-aware interaction for workflows like video editing and CAD.

Hyper Wheel XIAO: common questions

What microcontroller does the Hyper Wheel XIAO use?

The Hyper Wheel XIAO is built around the Seeed Studio XIAO nRF52840, from the Nordic nRF family.

How big is the Hyper Wheel XIAO PCB?

The Hyper Wheel XIAO measures 103.5 × 68 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hyper Wheel XIAO?

26 components, from 16 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 Hyper Wheel XIAO design files?

From the AnotherBuildCorner/Hyper_Wheel 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 Hyper Wheel XIAO design in my own project?

The repository has no license, so all rights stay with AnotherBuildCorner. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Hyper Wheel XIAO 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.
