AirGradient DIY v4

Support
#1

Hello,
I know that this setup is no longer supported, but I have a v4 board and soldered myself all the components.
Flashed the firmware via Arduino IDE and everything worked for around two hours. Then the display became static at the temp reading.

Turned off and on and now the display shows the message “init 1014”.
Does anyone have any idea what could be the issue?
Tried another SHT30 and result is the same.

I followed this guide:
https://www.airgradient.com/documentation/kb/kb-old-instructions-the-airgradient-diy-air-quality-sensor-basic-version-pcb-version-4-0/

Instead of the SHT40 I have an SHT30

Thanks in advance.

Hello @johnjohn, thanks for providing the log. I wonder if the issue still persists if the temperature and humidity sensor (SHT30 or 40) is not installed at all?

Hello @Tai_AirGradient ,

Yes, the problem persists. SHT30 sensor is installed.

Seems like screen is freezing and displaying “init 1014”. Installed a display test software and confirmed this.
Did some investigation and turns out the screen mentioned in the documentation, has this freezing identified behavior.

I bought a different one (0.96 inch model) and connected only the 3.3v pin and not the 5v.
It’s working and I will test and see if this one is stable.
