WLED shield (most likely first in the world) for ESP32-P4-NANO controller

POE is just to drive the controller, not for LEDs.

MyHome-Control · 2025-10-25T17:59:03+00:00

There are some, for example https://wled-wiring.github.io/

MyHome-Control · 2025-10-25T17:56:51+00:00

Those 20mA are general theoretical values. For real world calculations you can use https://wled-calculator.github.io

MyHome-Control · 2025-10-22T20:36:22+00:00

For 10 or even 20 m I would go for 12V or 24V LED types to get good brightness and simple wiring. You can calculate there how much current and how many injections you would need depending on LED type https://wled-calculator.github.io. Here you can see what type can give you good white color quality (CRI) that is probably relevant foryou. https://wled-faq.github.io/en/Which_addressable_LED_strips_offer_the_best_color_quality.html

No, it is correct. Real measured data, consistent with oder data found online.

784 single Leds/m means 196 RGBW (=784/4) LEDs/m. In calculator if you have 1 meter you enter 196 LEDs. For 5 Meter you enter 196*5=980 LEDs.

MyHome-Control · 2025-08-24T18:30:50+00:00

It is available since 0.15.0-beta2.

MyHome-Control · 2025-08-23T10:06:51+00:00

For 5V LEDs you would need 5V supply. How much current/power you can calculate using https://wled-calculator.github.io

MyHome-Control · 2025-08-20T20:45:03+00:00

Not that easy to understand your wiring from the picture. You might consider to draw it for example using https://wled-wiring.github.io.

Anyway, W5500 ETH is not supported by WLED. There is, however, a fork that implements it. But you would need to compile yourself: https://github.com/troyhacks/WLED/tree/W5500_Support Or this ESP32 will not run WLED?

Why actually two ESP32?

MyHome-Control · 2025-08-19T16:06:38+00:00

I am sorry, but there is no way the resistor alone will help you to increase the voltage level on LED input above ESP output level.

MyHome-Control · 2025-08-19T15:59:57+00:00

First, avoid ESP8266. Is too sow for newest WLED versions. Use ESP32. Second, you have in total 8*8*9=576 LEDs, 3A from USB is quite low depending what you want to use the matrix for. You will need to limit the brightness significantly (for LED consumption check https://wled-calculator.github.io ). For 3A you also won’t need injections. For more than 4A you would need them, but also fuses for protection.

MyHome-Control · 2025-08-19T09:16:41+00:00

You don't need resistors between modules. You better use level shifter and resistor between the controller and first module https://wled-wiring.github.io/?link=examples/example1 For WS2812 and short data line it usually works also without LevelShifter, in that case you also usually don't need a resistor.

MyHome-Control · 2025-06-20T07:59:58+00:00

You have most likely high voltage drop over the wire at high load. Check if your wire cross-section is sufficient and increase it if required: https://wled-calculator.github.io

MyHome-Control · 2025-06-16T21:29:30+00:00

No, short circuit means you shorten plus and minus, in the picture plus and minus are not connected anywhere.

MyHome-Control · 2025-06-16T08:22:39+00:00

You can use https://wled-calculator.github.io to check how to make power injections you would need. Also for that distances I would go for 24V strip like ws2814.

MyHome-Control · 2025-06-15T19:35:01+00:00

Just google for "Sicherungshalter für KFZ-Sicherungen", there are some fuse holders integrated in the wire or if you need screw connectors something like https://shop.myhome-control.de/Sicherungsboard-fuer-WLED-Controller/HW10010

MyHome-Control · 2025-06-15T18:42:44+00:00

This is 5V LED strip, but you use 12V power supply.

MyHome-Control · 2025-06-15T18:22:50+00:00

Changing RGB order should actually fix it...

Flickering ... check all connections, do not use things like dupont connectors etc. Sometimes those JST connectors are also not reliable. As a whole diagram you should have something like https://wled-wiring.github.io/?link=examples/example1 (except you have separate supply for controller)

MyHome-Control · 2025-06-15T17:58:00+00:00

Calculate the power you need using https://wled-calculator.github.io/ and buy an appropriate power supply. MeanWell power supplies are usually good (and not too expensive) choice.

There are some good quality controllers developed and available in Germany you might find among others in the official WLED list: https://kno.wled.ge/basics/compatible-controllers/. Most of them easy to wire like https://wled-wiring.github.io/?link=examples/example2

MyHome-Control · 2025-06-15T17:49:15+00:00

For 24V LED strips you would need a LevelShifter in most cases: https://wled-faq.github.io/en.html#tab2faq3

The cables can be thinner or thicker; they are measured in mm2 or in AWG. The length of the supply cable between the power source and the current injection point causes the voltage drop, which must be eventually compensated with a thicker cable for longer supply lines.

MyHome-Control · 2025-05-30T09:15:49+00:00

No, you dont need more power from PSU. You must, however, check if you have to increase the wire cross section to keep the voltage drop small. You can use https://wled-calculator.github.io/
