This is an 8-Output driver board for WS2811/WS2812 LED series. The board uses WT32-ETH01 microcontroller with ethernet to control LED strings. Listing is for board only, WT32-ETH01 microcontroller with ethernet should be purchased separately

There are two forms of WT32-ETH01 microcontroller boards available due to the way the header pins are soldered to the main microcontroller. This board accepts either form factors (Non-Flipped and Flipped), there are two sets of female header connectors that accepts flipped or non flipped WT32-ETH01.

Power Supply

Board can be powered using voltage that ranges between 5v to 32v, there is an onboard converter that powers the microcontroller and level shifters with stable 5v and user is free to use LED that are 5v, 12v and 24v without the need to set any jumper pins. Board is also protected against reverse polarity, meaning if the power input is connected the wrong way, the board will simply not turn on. However, the connected LEDs are not protected (although LEDs typically will not allow current to flow the wrong way, but efforts should be made to not run LEDs with polarity reversed, or they may be damaged). All the 8-outputs are individually fused with 5A blade fuses that can be easily replaced.

Fan & Temperature Sensor

There is on-board standalone fan controller that can be used to control at least two 5v fans when the controller is used in an enclosure. There is a sensor that controls the fan speed based on how hot the enclosure is

Board Programming

The WT32-ETH01 can be programmed using the provided micro-USB connector. Simply attach WT32-ETH01 and connect the board to a computer USB and flash the WT32-ETH01 with either WLED firmware to control LED strings. It is recommended to not connect this board to a computer USB at the same time connect power supply to the power input on the board to avoid damaging either the board or computer.

Header Pins

There is header pin for one standard input, a ground and 5v that can be used for audio reactive WLED and any other use as appropriate

Testing

The board is made to handle high current from connected LEDs due to wide traces and extra conductive materials added to the power traces. During testing, we were able to connect 300 LEDs on each output making a total of 2,400 LED without the need for power injection at 170 brightness level of white on WLED application thereby drawing close to 20A of current for over one hour.
