WS2811 WS2812B LED Controller Bluetooth Music with MIC for SK6812 WS2812 Pixel LED Strip Light APP 28Keys Remote USB 5V

Worked great and connect easily with the LED strip. My phone easily scanned the QR code to download the app. App is easy to use to control the lights.

Ended up returning. Not very customizable. OK for beginners. Just has the basic “gas station window” settings. Not many options for gradients or more mature blends.

I bought some of these when I couldn’t get an 8266 board for my 3d printed lights. Cut off usb end and hard wire to usb c port, works great. App is clunky at times but one of the best options out there. And love how they include a remote as well! Just wish the remote came with a battery!! Only complaint.

Lights work fine while using the app and have the listed features. I couldn't get the remote to work. After a while I popped the cover open to check out the inner workings. I've worked in electronics manufacturing for over 20 years, and I can tell you that this model I received did not have an IR sensor on the pcb. There is no way that the included remote can communicate with the LED's. I'm going to keep them and use them with the app functionality, but am severely disappointed that a remote is included in the package when it's not even designed to work with the product. Seems to work fine as long as you don't mind the remote not working.

The convenience of having a ready to go controller is wonderful. I was using Arduino nano clones in the past to do what this does out of the box. The plastic shell can easily be removed and heat shrink applied over the controller to minimize the volume of space consumed by the board. I have not used the available mobile app to control these, but the included remote has enough options out of the box to be a solid implementation. Unlike some other models, using a small switching buck converter has no untoward effects on the performance of this controller. I have experienced an issue with other solution where the switching noise from the step down converter causing odd behavior... It appears they applied sufficient power filtering of the input as to ameliorate the potential of this issue to arise.

Wow! Having bought over 30 WS2812B LED Controllers, I have a new favorite. Normally I use a SP107E, but this weird brand, "Vrabocry" has made a solid product. Though it comes with an infrared remote, it's really intended to use a Bluetooth app, which has a bunch of different LED patterns, including sound-reactive. A major benefit of this unit is its small size, perfect for clothing LED mods where things need to be lightweight and small. Microphone has great sensitivity too, really impressed, great product! I just bought three more since I don't know how long this model will be available. Enjoy, and light up the night!

It works fine but app doesnt work right , when u want a costom green color it gives another color(red)after thinkering it finally gave me the color i wanted

Perfect replacement for my original controller
