Allows you to use the Arduino as a DMX master device
This Velleman DMX512 Connector Module allows you to use the Arduino as a DMX master device (transmitter). This board is a simple circuit based on a driver chip (MAX-485 or SN 75176). With XLR 3 pin male DMX output connector and an impedance is 100 Ohm.
Pin1 = Signal Common, Pin2 = Data-, Pin3 = Data+
The board converts the Arduino signal voltage according to DMX (RS485).
