We recently upgraded our Genesis V1.3 system to a V1.5 system. Since the upgrade, we have noted a low voltage status in our Raspberry Pi status in the Connectivity Widget. Has anyone seen this status after a similar upgrade and know what can be done to address it?
I had the same question when I originally built my V1.5. It turned out to be nothing.
The following thread will have more details:
Hope this helps…
The low voltage indicator can impact the camera performance (blank or dark photos can result) and it can cause other Raspberry Pi performance issues. You can eliminate this low voltage indicator by replacing the USB cable. Unfortunately the USB power cables are causing too much voltage drop and these cables are one of the contributing causes of the low voltage indicator warning.
The other cause of the low voltage indicator warning is the fact that the Farmduino is not supplying a high enough voltage to begin with. Please review this troubleshooting documentation if you believe your Farmduino is not outputting a high enough source voltage:
To resolve the low voltage indicator you will need to replace the USB power cable going from the Farmduino to the Raspberry Pi. This USB cable provides power to the Raspberry Pi from the Farmduino’s built-in 12v to 5v to USB circuitry. We would suggest getting a high quality replacement for this cable.
Connector 1: Right-angle USB 2.0 Type A Male
Connector 2: Right-angle microUSB 2.0 Male
This is a product that will be a functional replacement.
There are other USB power cable products that may also work for this application but they are not listed here.
You will need to find a high quality replacement for this connector and that will eliminate the low voltage indicator.
