About the Aura a03-before second placement refinement PCB

Aura a03-before second placement refinement is an open source Nordic nRF PCB design by Avinash1286, published on GitHub under the MIT license. It is a 4-layer board measuring 24 × 42 mm, with 61 components from 34 distinct parts.

Its main chip is the MDBT50Q-1MV2, from the Nordic nRF family. Other key parts include the W25N01GVZEIG, BQ25185DLHR, TLV75530PDBVR, MAX17048G+T10 and DRV2605LDGSR. By type, the board carries 22 resistors, 18 capacitors, 9 ICs, 4 connectors, 2 microphones and 2 switches.

It belongs with the wearables designs in this gallery.

From the project

AURA: open wearable note-taking device development — PCB, printable case, firmware, Next.js/Convex notes, interactive 3D site and launch film.

This directory does not contain a fabrication-ready PCB release. Do not order the placement export or standalone session.

See ../../docs/hardware.md for charging, cell, RF, acoustic, mechanical and software qualification limits. The earlier connector SES import was cancelled without an explanation. No alternative import was performed to bypass it. A standalone routing session is not an independently checked routed KiCad board.

The KiCad project lives in the Avinash1286/pendent repository on GitHub; these links point at the commit this page was built from.

Aura a03-before second placement refinement: common questions

What microcontroller does the Aura a03-before second placement refinement use?

The Aura a03-before second placement refinement is built around the MDBT50Q-1MV2, from the Nordic nRF family.

How big is the Aura a03-before second placement refinement PCB?

The Aura a03-before second placement refinement measures 24 × 42 mm, has 4 copper layers and is 0.8 mm thick.

How many components are on the Aura a03-before second placement refinement?

61 components, from 34 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 a03-before second placement refinement design files?

From the Avinash1286/pendent repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Aura a03-before second placement refinement design in my own project?

Yes, under the terms of its MIT license, which Avinash1286 chose for the repository.

Can I test firmware for the Aura a03-before second placement refinement 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.
