Top Positive Review

I initially encountered issues with this controller, but all is well now! I am using the BTF-Lighting 5VDC 20A power supply which does not maintain 5VDC under the load of a 5m LED strip. When voltage drops to 4VDC this controller will not respond. (This is likely not be a concern when using 12VDC LED strips.) I was able to work around the low voltage issue by powering the controller from a separate power source — I happened to have a 6VDC power supply with correct polarity on the barrel connector. I disconnected the red LED strip wire from the controller VCC and connected the spare power leads from the same end of the strip to the power supply (white & green to the controller, white and red to the power supply).

Using this controller with a SK6812 RGBW (natural white) LED strip, I am able to select any static color for the entire strip, including RGB white and natural white. There are also 200 light patterns from which to select the effect of chasing lights in multiple color options. The brightness and speed of the selected color or pattern can be adjusted. Under ‘settings’ you can specify the number of pixels you wish to have lit. I’ve seen it mentioned to always select 2048, but selecting more pixels than you have on the stip only causes the pattern speed to slow down.

Top Critical Review

I’m using a SP105E Bluetooth controller with 5m 370 leds WS2812B strip on a 5v 10a power supply. The app is configured for 36 leds on WS2811 chip.

Initially I could not get the controller to stay connected while powering the lights through the DC output of the controller. When the light strips were disconnected from the controller’s DC output, the Bluetooth connection was constant and never dropped out. The 5-24 voltage regulator of the controller cannot take the voltage dip of the inline LED strip.

Once I used a separate 12v power supply for powering the controller and a separate 5v supply for the strips the BT connection and data output were constant. Although I had full connection and data output, the controller would not output to the proper number of LEDs or display static colors.

All in all, if the Controller properly displayed selected colors it would be useful to test strips but the lack of configuration ability in the app is lackluster.

Customer Questions & Answers

With this are you able to have the LEDs change from one color to another, for example red to orange along the length of the strip?
Answer: I have the app on my Samsung S7 edge and I can control the leds with any color i want.

I can also set it on random and it goes thru 200 sequences over and over.

Hope this helps.
