Wonder if someone can check this circuit diagram for me and make sure I am going down the correct route. I am creating a controller to control two sets of LEDs. One 24 strip, and one set of 12v uplighters.
I am using a Micro. This is what I have so far. The individual components are linked at the bottom. My background is software engineering so the diagram might not be perfect and hence why I am double checking. Note I have left off resistors, capacitors, MOSFETs etc for now for clarity as I am just focusing on power.
So I have a 150w 24v LED driver wired to the mains. From that I am using a step down converter to 12v to power the arduino and the uplighters. Then a buck converter to output 3.3v for the fussy ESP8266. Grounds all wired together.
Does this look sensible? One possible mistake I have made is the LED driver is rated at 150W. The LED strip was quoted at 14w per meter. However, what I missed was the RGBW version which I have is rated at 23W per meter. So the LED strip and downlighters are already taking me over 80%. Although only slightly and I doubt the Arduino and ESP board will draw much. But possibly I need a higher rated driver.
Parts (I am ony allowed 2 links as new user so have put a dash in front of the others)
