WS2811 SPI DC 12 to 48v Strip and module addressable decoder - Addressable Anything
This controller is designed to decode SPI (Serial Peripheral Interface) signals and control DC
loads, likely for LED lighting applications, given the mention of a "Dimming Channel" and an IC
commonly associated with addressable LEDs.
Key Features and Specifications:
● Type: SPI (DC) Decoder
● Integrated Circuit (IC): WS2811
○ The WS2811 is a popular LED driver IC often used with addressable RGB LED
strips (like WS2812B, which integrates the WS2811 driver). Its presence indicates
that this controller is likely designed to interpret data protocols similar to those used
for controlling individual LEDs or segments in addressable LED systems.
● Dimming Channel: Red Color
○ This suggests that the controller might specifically manage the dimming of the red
color component in an RGB setup, or it could be a single-channel dimmer primarily
for red LEDs. It's also possible "Red Color" is just an example or highlights a
specific dimming capability within a broader range.
● Maximum Load Output: 3 Amps
○ This specifies the maximum current that the controller can supply to the connected
DC load. It's crucial not to exceed this limit to prevent damage to the controller.
Connections:
The controller has distinct input and output sections for both data and power.
Left Side (Data & Input DC Power):
● DC: 12-24V: This indicates the input DC voltage range for powering the controller itself. It
can accept a wide range from 12 Volts to 24 Volts DC.
● Data In (→): This is where the SPI data signal (or a compatible serial data signal like
WS2811 protocol) is fed into the controller.
● Data Out (←): This likely provides a data passthrough or a buffered output of the data
signal, allowing for cascading multiple controllers or devices.
Right Side (Load DC Power & Output):
● DC In: 12-48V: This is the input DC voltage for the actual load that will be controlled. This
wider voltage range (up to 48V) suggests it can handle higher voltage DC loads than the
controller's own power input. This might be for powering LED strips or other DC devices
directly.
● DC Load Out: This is where the controlled DC power is supplied to the load (e.g., LED
strips, lights). The controller will modulate the power to this output based on the incoming
data signal and the dimming settings.
In summary, this SPI (DC) Decoder is a versatile controller for driving DC loads, particularly
suitable for addressable LED applications using the WS2811 protocol, with a specific focus on
dimming and capable of handling up to 3 Amps of load current. It requires separate power
inputs for the controller logic and the load it drives, offering flexibility in power supply choices.
