Module with part number EA DIPS082-HNLED comes with yellow/green LED backlight. Power consumption for backlight is 50mA typ. and 80mA max. Backlight is permanent switched on. Supply voltage with backlight is 5V only. For individual use LED backlight can be switched on and off after doing the following modification: Remove series resistor R5 and change resistor from R6 to R7. Now a positive voltage at pin 7 (D0) powers Anode of backlight direct. To limit LED-current an external series resistor is required (R = Ext. 0,8V / I ). Please note that in this case display interface is 4-bit mode only LED Table of commands Code Execute Instruction Description Time DB DB DB DB DB DB DB DB R/W RS 7 6 5 4 3 2 1 0 (max.)
