About the Aura a03-before placement refinement PCB

Aura a03-before 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 placement refinement: common questions

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

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

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

The Aura a03-before 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 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 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 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 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.
