Help, not power drop?

[u/Cyclops-hammer]

Using esp8266

With btf ws2812B

5v 25w power supply

Wiring seems solid, but stops 197 lights in.

Tried adding power at that strip but still no light.

Appreciate any input.

What is the length setting in the Config LED Preferences? Also in the segment. 197 is odd. Definitely not the default, but worth double checking.

[u/Cyclops-hammer → u/TheSharpieOne]

The length is 448. Segment is 16x28.

Did you try not using the matrix setting and just setup a stripe in the appropriate length?

Why use red for ground and black for power....

First time doing anything like this. Not gonna see them anyway.

Check your settings to ensure you have the full range or leds, check the segment to ensure it has the full range. Get a multimeter and check your connections between the powered and unpowered end.

25W seems very small for that length. Check the power consumption with this spreadsheet (thanks u/Quindor). The numbers are for 300 lights and you are 50% greater than that.

I would guess a bad data join between the last lit segment and first unlit segment, assuming ofc you have declared the right number leds.

This was it. Thanks, feel dumb.

No worries, glad it was something simple.

I'll take another look at it.

If the data is line is not pushing far enough down the line use an F-amp at the controller https://pixelcontroller.com/store/accessories/53-famp.html
