Yeah I have done that before with JLCPCB, but only tht componets soldered by myself. But I have the advantage that my company is the leading producer of Reflow soldering ovens so the LEDs should be no Problem ---

There you go. So it'll be a little quality test run of your ovens in other words 🙃 Well, I'll do another test run of the ol' bed here ---

I Cant use a traditional Strip. It will be on the ground, not lighting up a surface, it just needs to be visible as best as possible without blinding traffic. 20m Long with 40 LEDs so 2LEDs per Meter As a sort of guidance for drivers where to go ---

\*_Please note: these are high power LEDs, you need a strong 5V power supply that can provide at least 1/2 A per LED_ Is in the discription of the LEDs Wich means i put my Powersupply on the Vcc, with my data line coming from the arduino and my Ground being common between the two ---

Hi, @moax8898 Welcome to the forum. > [@moax8898](#): > > , they fit my Application really well What exactly is your application? What does your project do? Thanks... Tom.... 😃 👍 ☕ 🇦🇺 ---

50 x 350 mA = 17,5 A At 5 V you're gonna need some thick wires. Where will you inject? At one end, two ends or the middle), both ends and middle? One more thing, is there a possibility that people will walk over the installation, or tires run over? ---

ideally i would inject only on one end. You think 1,5mm² would be enough or should i use 2,5mm²? Tires and feet could happen but really only in a worst case scenario, so shouldnt be a problem ---

actually now that i think about it the middle would also be a possibility, so 10m in each direction ---

> [@moax8898](#): > > You think 1,5mm² would be enough or should i use 2,5mm²? No. To both mm². You will get voltage drop, especially if you power the strip from one end only. Ideally, you would use a higher voltage, with PWM. (That's why the MOSFETs are there for anyway). Lets see if there's a calculator out there. ---

> [@moax8898](#): > > Can i Put all LEDs on OUTR of the WS2811 and still control them seperatly or do need to put one on OUTB one on OUTG and one on OUTR Not to sure why you would want to use an LED driver to control a MOSFET switch but you do need to use **all 3** outputs AND they must be **pulled-up** to 5V. The logic will be inverted. You should also have a bypass cap on Vdd and series resistor in the data line. ---

So a MOSFET can be used to regulate Voltage? [Previous page](https://forum.arduino.cc/t/controlling-50-leds-individually/1353284.md?page=1) [Next page](https://forum.arduino.cc/t/controlling-50-leds-individually/1353284.md?page=3)
