GLEDOPTO ESP32 WLED LED Strip Controller with Mic Microphone Music Dynamic Mode RGB IC DIY Lighting App Easy Wiring for WS2811 WS2812 SK6812 TM1814 WS2813 WS2815 Addressable FCOB Strip Light

So I have mixed feelings about this product. I have at least six of this controller used with WLED and they do work good. Their big flaw is the wire connectors. I really wish they used standard Phoenix style wire connectors. You must push down on what looks like a plastic screw to open the wire jaw and then slide in the wire. Once the wire has been inserted you let up on the spring-loaded clamp. It is hard to push down and you feel like you will break it. Make sure you pull on the wire as many times it does not clamp correctly. It is so bad I saw another model that had levers but it was actually worse than this one. That all said, once you get your wires connected it really is a nice unit. I would say also they make an ESP32 and one that uses the lesser ESP8266. Make sure you get the ESP32 as you really do need the extra power of the Dual Core ESP32.

These have become my go-to WLED controllers. The fact that they have lever terminals, a barrel jack for power, and feature a SSR for power control, and support a variety of different voltages means that they have just about everything I could ask for in a simple controller. I've bought 3 so far and will happily continue to buy more as projects come up

Pretty straight-forward and easy to use/setup controller. Worked very well for my setup with WS2815 lights!

Setup was the easiest of my wled controllers due to the quick connects for the wires. Connected to the wled app right away and works seamlessly with my other controllers.I should have bought more with the sale price I got this one at!

It worked as advertised which for me is what is important. I just updated the installed version WLED to the latest is all and that went straight forward also.

The controller itself seems reasonably well designed and built, perhaps a bit overengineered. The quick-release connectors for the wires is quite convenient.However, the major flaw seems to be in the design of the output drivers. They had a fairly week pull-up, and with even a moderate amount of cable between the controller and my led strips (maybe 3m), the lights frequently flicker. I tried looking at the circuit to see if I could replace the pull-ups with lower valued ones to see if that would help, but as I said, it is a bit overengineered, as I mentioned, and the output driver circuit is overly complicated. It's too bad, because it looks like they tried, although I'm unclear why they didn't just use a 74HCT125 like most other controllers do.

The instructions show an internal USB port to reflash the code. These boards do not have any internal USB headers. They were flashed and then soldered to the boards.

I had some issues connecting the device to my strip, but customer service was able to resolve it for me
