Review on 🔌 Arduino Compatible CQRobot DMX Shield with MAX485 Chipset (RDM Capable) for DMX512 Network Integration, LED/Music Remote Device Management, and Extended DMX Master Capabilities by Robert Dabney

Good quality shield. I had an issue with corrupted output that turned out to be a library issue with the DmxSimple library. If you use this library, make sure you put: pinMode(2,OUTPUT);digitalWrite(2,HIGH);into setting void setup() so that it is passed correctly. Or set pin D2 low for receive. It's just that dmxserial works fine with this library, but you cannot use the serial monitor functions with this library unless you have an Arduino Mega and have configured the library to use other serial ports for dmx. The sign works well, asked the seller for advice on the board and there was definitely a language barrier but they were still keen to be helpful and provide useful information.
