PDM28 enable pin issue

The only way I can get my PDM28 to wake up is with USB connected to power. I've verified I have battery voltage on the enable pin (DTM B-1)

I am on firmware v1.1.1

Hi George, thanks for the reply.

In the UI, I read 13.3v for battery. When I measure voltage at the pin to the PDM ground, I measure 13.24V

The 5V rail in monitor is at 3.7V though

Hi Chris, email contact@hardwire-electronics.co.uk and we can take it from there. Sounds like there could be a hardware issue from your description.

Hi,

When you are connected to the PDM, what battery voltage to do you read?

You need power and ground on the main terminals, and 12V needs to be applied to the enable pin with respect to the PDM main ground.
