I am creating a scrolling sign using 3 panels a 16x16 and two 32x8 panels for a total of 768 LEDs the panels are 5V WS2812b originally I was using a 3A wall wart which was fine with 2 panels, but the third caused the ESP32 to shutdown. I should note that I did not put any capacitors on the power to the lights, there was no dimming with power injection, but I did add power injection anyways. I bought a 30A brick power supply ad everything works, but the power supply connector was burning hot. Is it normal for theses three small panels to pull that much power? I did look them up and it says they are rated for 50W which would make sense. Sould I have put a capacitor in the circuit?
Also, the text looks fine on a matrix 8 high, but I wanted it to be bigger which is why I was making mine 16 high, but increasing the font size only makes the text fatter, but not taller. Is there a way to make the text 16 pixels high?
I am a bit not clear on some of what is said but connector was burning hot is for sure a bad thing . I use a lot of those ws2812b eco( if you have the same ) and they do not need a lot of power but on low brightness but would for sure accept more if you allow it . ESP32 shutting down is also another bad thing i hope you are not powering any leds from the MCU pins . If you followed the KB wiring which i do for my panels then both issues should not happen . I do use a resistor and cap in all my builds because it is listed in KB .
For the part on the text on 16 high matrix it works perfectly fine on 16x16 , 16x32 and 32x32 ,might be i misunderstood the question , pics could help
Thanks, I will add the cap in, but looking at the KB wiring, it shows the resistor on the digital line and also said it was optional. Is that where you put yours?
I added pictures of the font. as you can see when I increase the font size it just gets fatter. I think I am just not seeing the setting for adjusting the height.
I see the text hight to be 9 leds ( 4 blank on the bottom and 3 on the top ) so in your case it is only 7 leds .
I used the nightly build from here WLED installation (wled-install.github.io) and the only thing i changed is font size
