I am looking at different boards to run WLED with my light strips, and looked at the SP501E because (in that order):
- it looks like a finished product
- it is compact
- it is cheap
I have also considered the QuinLED and Wemos shield options from the hardware guide, but thought I would try the SP501E first to see if it would fit my needs.
I am a massive n00b in electronics and would need some help identifying the components on the board to make sure it has all the features that are recommended by the WLED Wiki and the Neopixel Überguide.
I took the board out and it looks suspiciously simple. Could you please help me identify all of these components:
- step down converter: this is supposed to take 24V, 12V or 5V in and out, can one component really act as a step down converter for all of these voltages to power the ESP at 3.3V? Both the QuinLED and Wemos shield have a jumper to select which step down converter to use.
- capacitor to protect the board from the PSU: I guess there are plenty on the board
- resistor to protect the first LED: I guess there are plenty on the board, so there should be one for that
- logic level shifter to make sure the data wire gets 5V: I don’t recognise some of the components, maybe I am not look at it the right way
- relay to turn the power off: I guess there are non here, and the on / off button is really just a GPIO button
- MOSFET for the RGB pads: are these GPIOs, or are the small components next to them MOSFETs so you could actually drive 5/12/24V through these pads? They look really small to drive a few amps, but I am far from being an expert.
- How much power should I expect to drive through a board like this? It all looks really tight especially for 12/24V and decent amperage.
Thank you all for your help! Here are the board shots, in addition to the reference ones:
