PROJECT AURA PCB PREORDER. PCBs are expected to arrive late May to early June 2026.
If you are building a Project Aura Air Quality Monitor you already know the difficulty finding all of the components needed. The developer, 21CNCStudio has recognized the issue and has designed a custom PCB to replace most of the components.
You will no longer need:
| Part | Retail (USD) |
| Adafruit SEN6x Breakout for SEN66 | $4.50 |
| Adafruit PCF8523 RTC (STEMMA QT) | $4.95 |
| Adafruit BMP580 Pressure sensor | $7.95 |
| Adafruit Qwiic / Stemma QT 5-Port Hub | $2.50 |
| Aluminum Electrolytic Capacitor 10V 470µF | ~$0.50 |
| Seeed Grove screw terminal | $1.70 |
| Parts subtotal | $21.60 |
Some of the currently required cables will also no longer be needed. When the first PCBs arrive we will build a complete monitor to make sure we know exactly what cables will be needed. We also want to test the function for a few days before fulfilling orders.
This pricing does not include the shipping and possible duty/tariff fees required to get the components to your door.
You will still need the following components:
- Waveshare ESP32-S3-Touch-LCD-4.3 (800×480) !16MB Flash!
- Sensirion SEN66 This is the main sensor
- DFRobot SFA40 Formaldehyde Sensor
- 3D Printed Case. There are 4 options available from MangerMadeLLC or you can print your own.
- Required Cables
- Optional DFRobot Gas Sensors and DAC Analog Fan Controller
Pricing:
Pricing is simple $50 (plus tax) which includes shipping to lower 48 states. The PCBs will be shipped via UPS from Union, Ohio.
There are currently 20 PCBs in the first order. One will be retained for testing and quality control. Once 10 orders ae placed we will order an additional 20.
