About the AURA PCB

AURA is an open source ESP32 PCB design by YuvaKrishnaS, published on GitHub. It is a 2-layer board measuring 80 × 80 mm, with 16 components from 4 distinct parts.

Its main chip is the XIAO-ESP32-C6, from the ESP32 family. Other key parts include the 5050WS2812B and 47Ω.

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

A Github Commit Glowing Machine, that glows when I commit to github

A desk lamp that reacts to your GitHub activity. Pulses green when you push a commit. Turns dim red if you haven't pushed anything in 24 hours.

I built this because I wanted something physical that would hold me accountable.

Custom circular PCB, 80mm diameter, matte black. WS2812B ring around the perimeter pointing up , XIAO sits in the center on female pin headers.

AURA: common questions

What microcontroller does the AURA use?

The AURA is built around the XIAO-ESP32-C6, from the ESP32 family.

How big is the AURA PCB?

The AURA measures 80 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AURA?

16 components, from 4 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 AURA design files?

From the YuvaKrishnaS/AURA 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 AURA design in my own project?

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

Can I test firmware for the AURA without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
