The Industrial Raspberry Pi Forum

Good morning, I'm supplying the module with 24V, both on X4 and X2 and using a PIBridge plug to connect the DIO module (just purchased last week) to a RevPI Core 3 flashed with the latest Buster image and up to date updates. The RevPi Core 3 is powered from the same supply.
I have read that the Power LED on the DIO can flash when the supply is below 19V but this is clearly not the case.

Any idea why it flashes?

Thank you,
Micha

After a bit more testing I noticed that after about 30 seconds the DIO Power LED turns green (probably when Core 3 boot process has finished).
So it looks as if all is working ok.

However, I wonder if you might want to rethink the operation of this LED:
When the user is shown a flashing red Power LED, I think it's pretty normal to think that something is wrong and the power supply switched off quickly to prevent any damage.

Thanks,
Micha

Hello michasch,

it is correct, the products is as it shoud be, at the beginning the DIO flashes red and then after 30 seconds it will turn into a green flashing light.
