I was wondering how I could implement the DMXBridge with a Wemos mini Pro (esp8266 based board, more universal pins, more memory and integrated WiFi).
So I don't need a nRF24L01+.
Now I found a Instructable to make the DMXSerial work. (http://www.instructables.com/id/ESP8266-Artnet-to-DMX/)
But I need to make the data transmission between the sender and multiple receivers, like this product works: http://wirelessdmx.com/products/micro-f-1-lite-g4s
