This is a 2-universe DMX decoder shield and power supply for the ESP32 and 8266 Lolin Wemos Boards.
This board iteration (v2) is discounted because it needs a few wires in addition to the PCB for the fully assembled product.
I have a lot of DMX lighting that I would like to run but without wires and using open-source hardware and tools. This board works for DMX lighting strands (raw wires) and DMX hosts with 3 pin connectors. It takes 5-24 volts as VIN and regulates that power to run the NodeMCU and the DMX translation chips.
It replaces typical Arduino DMX shields for one that is integrated with the Wemos D1 Dev Boards. It also integrates a 5v power supply reducing the number of external components. Since this board is wireless and relatively inexpensive, the cost and complexity of isolating the output from the low-voltage side of the board did not make sense.
The board has broken out unused pins from the MCU allowing for easily adding in extra LED pixels, sensors, etc. It has 2 indicator LEDs as well allowing easy status updates for debugging or connection updates, etc.
The board can be powered from:
This product is fully assembled and includes a Wemos D1 Mini ESP32 socketed with headers for easy replacement in case of issue. The board supports 2 DMX universes but comes configured with WLED that only currently supports 1 DMX universe.
Min input voltage: 6v (5v if using USB from D1 Board) Max recommended input voltage: 25v
5V power is to run the ESP board, DMX is not opto-isolated since the board is fully contained (wireless) and not connected to other devices).
Width: 66mm Length: 46mm Height: 34mm (with headers) 20mm (without headers)
