Aura PCB
Combined PCB for Aura Air Quality Monitor builds.
A single compact board that combines parts you would normally purchase separately — designed around the Project Aura firmware and enclosure. Cleaner build, fewer cables, less to source.
On the board
- BMP388 (atmospheric pressure)
- PCF8523 (real-time clock)
- Direct connector for Sensirion SEN66 (CO₂, PM, VOC, NOx, temperature, humidity)
- I²C ports for the sensors Project Aura currently supports:
- CO sensor (carbon monoxide)
- SFA40 (formaldehyde / HCHO)
- DAC (1–10 V output for HVAC / ventilation control)
