  • Made in Germany
  • CE, RoHS, WEEE

Basics#

The cod.m WLED LAN Controller enables WLED installation in the distribution cabinet or in the sub-distribution board. With the Range Extender OUT module, the LED strips can be placed up to 250m away from the controller. Alternatively, LED strips can be operated up to two metres ditance with the Direct OUT module. The power supply for the strip (load current) is completely separate from the controller. For multiple power feeds, we recommend using our WLED Fused Power Capacitor Board. If you have multiple power feeds, ensure that the fuse is of the appropriate size.

Data signal#

The data signal of the digital LED strips (WS281x, SK6812, etc.) can normally be used safely up to two metres from the controller. Each LED regenerates the data signal, allowing a distance of two metres between the LEDs.

If the controller is installed centrally (e.g. in a sub-distribution board), it is of course not possible to install all LED strips at a distance of two metres. For this reason, we have integrated the principle of the WLED Range Extender into the WLED LAN Controller.

The basic configuration of the WLED LAN Controller includes a WLED LAN Controller Range OUT Module (item no. 90656) for plugging onto the controller and a WLED Range Extender OUT (no. 90066). Additional WLED Range Extender OUT boards and plug-in modules can be ordered separately.

Segments#

For WLED, all connected LED strips together form one logical strip. This means, for example, that an effect runs from the first to the last strip as if it were a single long strip.

If, for example, you install strip 1 in the living room and strip 2 in the hallway, WLED cannot distinguish between them at first. The solution to this is called segments: In the WLED configuration, you can define segments for parts of the strip that can be controlled separately with minimal restrictions. You can either create these segments manually, which also allows you to subdivide them, or, starting with WLED version 0.15beta, you can have a segment created automatically for each connection on the controller when configuring the strips.

Automatic segments

Segments can be controlled as desired in the WLED web interface as well as via the interfaces.

It therefore makes sense to name the segments accordingly so that they can be easily assigned.

Warning

When using presets, the selected segments are also saved. This means that effect overlaps may occur. Please pay attention to the assignment of the segments in the presets.

Info

With the current WLED version 0.15, timing problems may occur with effects, which are noticeable by brief flickering of the individual segments. In this case, simply change the effect speed slightly.

Slots#

The WLED LAN Controller offers two slots for output or input modules.

Slots WLED LAN Controller
Slots of the WLED LAN Controller
  • GPIOs 15, 16, 4 and 5 are available in the left slot (1). On the output module, these correspond to GPIO 15 and 16.
  • GPIOs 13, 14, 33, 34, S_VN and S_VP are available in the right slot (2). On the output module, these correspond to GPIOs 13 and 14.

Currently available modules#

Further modules are planned for the future.

Connections / GPIOs#

WLED LAN Controller GPIO output
GPIOs used depending on module position

Depending on whether an output module (OUT module) is plugged in on the left side (1) or the right side (2), different GPIO must be configured. The pins used by the module are documented on the circuit board. The logic is highlighted again in the image above.

The LED strips are connected according to the connection diagram depending on the module used.

When connecting the Range OUT module, please always follow the instructions in the WLED Range Extender.

Configuration#

WLED LED configuration
WLED LED output configuration

Under LED Preferences, configure your LED strips according to type, length and connection (GPIO). Then divide the connections into segments to allow separate control of the connected LED strips. Please always follow the instructions under Segments.

After configuring the connections and segments, you can use the individual segments of the strip separately via the web interface or the interfaces with minimal restrictions.

Configuration after factory reset#

After a factory reset, you must first establish a connection via Wi-Fi with the access point wled-ap and the password wled1234. Then, under Wi-Fi Settings at the bottom, select ESP32-POE under Ethernet Type. After restarting, the WLED LAN Controller can be accessed again via the network connection.

If the GPIOs 15, 16, 13 or 14 cannot be selected in the LED configuration, please check under Usermods to see if they are assigned there. After deselecting the pins, please restart the controller. From then on, the GPIOs can be used as usual.
