A quick search leads me to believe that any GPIO pin can be used for PWM on the ESP8266 (not the case for all MCUs). ![]() Maybe it's the interconnecting wires or your power supply isn't able to deliver the current you need. Yes, PWM on RGB LEDs can produce all colors. So, my conclusion is that it can't be the MOSFET that's giving you the problem. Note - the current is about 13 amps.Ĭan you see that the 2nd line I drew (the horizontal red line) crosses a bunch of traces in figure 1? It doesn't cross the lower trace (not quite) and that is the trace when \$V_\$ voltage of only 3 volts. Now, at the point where the red line hits the traces if you looked across at figure 1 you can see what that means. In the datasheet, it says min logic level on Gate is 4V, on ESP8266 I have 3.3V. It is 3.3V logic, so the focus is on the logic level. So, on the graph on the right (the one you used) I have marked a vertical red line corresponding with a gate source voltage of 3 volts. ESP8266 and RGB LED strip Using Arduino General Electronics whotookmynick August 15, 2021, 10:21am 1 I am using IRLZ44 to power 12V RGB LED strip with an ESP8266. I have a multimeter, just wouldn't know where to even start measuring things.Īlso I'm not connecting the MCU to 12V as I know that's too much for the voltage regulator, I just couldn't find a good enough cirtcuit drawing tool, so any suggestion for that is welcome as well.įortunately, the graph you want is actually next to the one you used and I have marked red lines on to explain where you problem is:. (However it is my first time looking at a datasheet so that's probably where my mistake is, though I have no clue what). Looking at the datasheet for the MOSFETs, it looks like at 3V G_gs is should let through 10A, way more than the 0.5 I require. The circuit is very simple, strip (5m, 30 leds/m) runs on 12V and should take 1.5A, so 0.5A for each channel, and that's what the power supplies. Also, there seems so be a quiet high pitch sound when using the transistors. The main problem SEEMS to be the mosfets, as if I connect the LED strip chanels directly to ground i get a much much brighter light. (I saw the similar question, however my transistors are definitely logic-level) However, the strip is not nearly as bright as with the original IR controller. So, I'm trying to control a LED strip with a NodeMCU using N-MOSFETs FQP30N06L, one for each channel. ![]()
