This ready matrix consists of 64 pixels with WS2812 LEDs in 8x8 arrangement. Each pixel is individually controllable via a suitable driver. The matrix is still somewhat flexible in the size of 8x8cm. Several of these panels can be connected very easily. So you can quickly build a larger system.
The control is done by digital LED drivers, which support this LED type (WS2811 or WS2812). Available are drivers with SD card and also online drivers, which are controlled via Ethernet. An animation software is included with the driver.
The drivers for digital LED strips are specially designed to control as many RGB pixels as possible individually.
With the LK63, up to 5.440 pixels are possible, divided into 16 channels with 340 RGB pixels each. This corresponds to a total of 32 DMX universes, which are transmitted via LAN/ArtNet.
The 16 pixel outputs can be loaded with max. 3 amps per channel. For larger installations, the pixels can and should be powered separately. The controller then supplies only the data signal (DATA). Pixels with and without CLOCK signal (CLK) can be controlled. Pixel types with CLK are e.g. WS2801 or APA102. The controller can be controlled via ArtNet and offers 2 additional DMX-OUT ports with 512 channels each. For configuration, the controller has an integrated web interface as an alternative to direct input on the display. The configuration options are very extensive: selection of pixel type and color sequence (RGB, RGB, GRB etc.) flexible addressing (DMX-Universe and start address individually for each of the 4 outputs) number of pixels to control per channel (0-340 pixels - e.g. to save DMX universes) number of zero pixels to skip first unused pixels in an installation Zig-zag or backward addressing of pixels for matrix applications
Brightness limitation per channel
In addition, the controller offers a test mode to test the installation with various effects (Chase, Dots, Rainbow, ...) and static programs (all pixels red, all pixels white, ...) even without an applied ArtNet signal. The speed of the effects can be varied.

The SP108 can drive up to 2,048 pixels and many different pixel types: WS2801, WS2811, WS2812, SK6812, APA102 and many more.
The suitable app "LED Shop" is available for free for IOS and Android and offers 180 different chase effects as well as precisely adjustable single colors. Speed and brightness can be changed at any time. A handy feature is that you can choose your favorites from the 180 effects and then quickly select them.
Setting up the driver is quite intuitive and done in a few minutes. The driver works in the 2.4 GHz WLAN and can be accessed directly via the smartphone as well as integrated into the home WLAN.

Does the driver require an existing WLAN?
No, the driver can also be controlled directly with the smartphone (AP mode) and offers its own WLAN access point ("SP108E_xxx") for this purpose. If a WLAN is available, the driver can alternatively be integrated into it (STA mode), so that the WLAN does not always have to be changed to operate the driver.
Can multiple drivers be used simultaneously in the app?
Yes, the app can manage multiple drivers at the same time. You can switch between the drivers and change the settings for each. In addition, the individual drivers can be switched on and off directly. However, there is no direct synchronization and each driver must be set accordingly for itself.
Does the app have to be active for the animations to run?
No. The app is only needed for the setup. You can close the app afterwards and also turn off the smartphone, for example. The SP108 will continue to play effects.
Does the driver keep its settings when it no longer receives power?
Yes, the driver can simply be disconnected from the mains. When power is applied again, it will start with the previously set animation. All settings will be kept.
How can the white LEDs be used, e.g. with a SK6812_RGBW?
The app has a separate control for white LEDs (e.g. for SK6812_RGBW pixel strips). This can be used to set the proportion of white LEDs and then, in the case of effects, the white LEDs are taken into account accordingly, so that the colors are generally desaturated. In the effects section of the app, the SOLID setting can then also be used to activate a permanently white, high-quality light, e.g. for lighting tasks, if required.
Can the SP108 also control LED matrices?
A number of pixels and a number of segments can be set in the setup. For example, for an 8 x 8 matrix then 8 pixels and 8 segments. This is taken into account in the effects, but in most matrices the pixels are connected in a snake shape as a long line and this is unfortunately not taken into account by the SP108. Therefore the effects are not displayed as desired on the matrix, but every 2nd row of the matrix shows the effect quasi upside down. We hope for a technical improvement here soon.

Protection circuit for WS2812-stripe and matrix systemsAt WS2812 the WS2811 is already integrated in LEDs and allows the digital controlling of pixel. Most common is the LED-stripe with WS2812. The available version WS2812B can be very sensitive to voltage peak and ESD. A small cuircuit has been developed to mostly prevent a destruction of the first pixel. A small board is linked directly infront of the first pixel. The board has been designed that a directly connection of a LED-stripe is possible. The connections has to be identical with these of the board.One aspect of the circuit is the serial resistor of 270 Ohm. If you have such a resistor already present on the LED-stripe, you can override it, if it causes difficulties in operation-
