Duet 3 Mini 5+ 5V current limit enough for 3 NeoPixel LEDs?
-
Hi dear community,
I want to add a Voron Stealthburner printhead to my new build which supports three NeoPixel LEDs.
The documentation tells that NeoPixels are supported but the 5V current on a Duet 3 Mini 5+ is limited to 1A so an external supply is required for a strip. But I want just three LEDs.
Each LED is rated about 60mA full bright white.
I have also a PanelDue 5i connected and the X/Y hall effect sensor on 5V.
The documentation also says internally the board uses 200-300mA, for the PanelDue I just find some only ratings between 280mA for 4.3'' and 650mA for 7''. No idea what the hall effect sensor board is rated but I don't think thats is much.
So lets assume 180mA for all three LEDs, 350mA for the PanelDue 5i and 300mA internal I use up to 830mA.
Is that reasonable?
Or is that too close to the maximum and what about 3.3V?
Is there and internal 3.3V usage?
I use 3.3V just for the Z endstop switch and a PINDA Z probe.Cheers

@alex9779 830mA total load should be OK.
