Project Aura 4.3″ Backer Hardware Kit

Project Aura 4.3″ Air Quality Monitor – Backer Hardware Kit

Bring professional-grade environmental tracking to your workspace or homestead with the Project Aura 4.3″ Basic Kit. This comprehensive hardware bundle includes the core components needed to build our signature, high-accuracy air quality monitoring station.

Designed for makers, developers, and power users, Project Aura pairs a responsive, high-resolution visual dashboard with industrial-grade sensing capabilities—giving you real-time data on your environment exactly where you need it.

📢 Attention Project Backers: This hardware kit is specifically curated for our project backers who have access to the official STL files. Grab this bundle to get all the core electronics needed to populate and build your Project Aura. The Project Aura Backer Hardware Kit does not include the 3D printed enclosure.  It is designed to supply all components for the project backers to build a Project Aura along with their 3D printed enclosure.

Looking for a larger display? We also offer a Project Aura 7″ Display Kit for those wanting an expanded visual dashboard. Check out our store page for availability.

What’s Included in the Basic Kit

Every kit ships with the primary hardware components required for assembly:

• Waveshare 4.3″ Touchscreen & ESP32-S3 Development Board: A bright, responsive, high-resolution capacitive touch panel powered by an integrated onboard ESP32-S3 microcontroller. It handles both your UI rendering and sensor processing on a single, powerful board.

• Custom Project Aura PCB: Our custom-engineered interface mainboard designed for stable power delivery, clean data line routing, and seamless component expansion.

• Sensirion SEN66 Sensor Module: A premium, all-in-one environmental sensor delivering highly accurate, laboratory-grade telemetry for particulate matter ($PM_{1.0}, PM_{2.5}, PM_{10}$), total volatile organic compounds ($TVOC$), nitrogen oxides ($NO_x$), temperature, and relative humidity.

• Premium Assembly Hardware: All necessary machine screws, standoffs, and fasteners required to securely mount the electronics inside your printed housing.

• Interconnect Cables: Complete wiring harness for seamless, plug-and-play connections between the custom PCB, sensor, and display—no tedious jumper wire routing required.

Expand Your Build: Optional Add-ons

Take your environmental telemetry to the next level with these drop-in hardware expansions, fully supported by the Project Aura architecture:

• DFRobot SFA40 Formaldehyde (HCHO) Sensor Module: Adds dedicated, high-precision electrochemical sensing to detect low-level formaldehyde concentrations with excellent cross-sensitivity resistance.

• DFRobot SEN0466 Carbon Monoxide (CO) Sensor: Integrates a robust, factory-calibrated CO sensor into your stack, essential for critical air quality and safety monitoring.

• DFRobot GP2Y1010AU0F (DFR0971) DAC Module: Expand your hardware interface capabilities with this precision digital-to-analog converter, ideal for integration with external analog logging equipment, legacy hardware, or custom automation triggers.

Key Features

• All-in-One Processing & Display: By leveraging the Waveshare ESP32-S3 HMI architecture, your display doubles as the central processor, minimizing wiring clutter and optimizing performance.

• Industrial-Grade Accuracy: Equipped with the Sensirion SEN66, this kit handles heavy environmental monitoring with advanced optical particulate sensing and long-term calibration stability.

• Modular & Expandable: A versatile PCB layout that makes it easy to plug in specialized gas sensors and analog output modules as your monitoring needs evolve.

• Optimized for 3D Printing: Perfectly matched to the project’s official backer STL files for a seamless, satisfying assembly experience.

⚠️ What You’ll Need to Provide:

• CR1220 3V Lithium Coin Cell Battery: Required for the onboard Real-Time Clock (RTC) to maintain time tracking during power cycles (not included in the kit).

• Power Supply: A high-quality USB-C power supply.

• Enclosure: Your printed housing using the project’s backer STL files.
