Product Name: LCD1604 Display Module 5V Screen for Uno R3 Model NO.: NA020 Display Technology: TFT Type: Color Usage: Small-sized LCM, for Arduino Trademark: KS Transport Package: Antistatic Bag Specification: 20g Origin: Guangdong, China(Mainland) HS Code: 9013803020 Product Description LCD1604 LCD screen 1604 display module 5V blue screen For UNO R3 Features:Shape size: 86.96*60*13mmDisplay area: 62.3*27.6mmCharacter number: 16*4Glass type: yellow green film / blue film / gray film / black filmBacklight types: yellow green light / Blue / White / red / Emerald lightDrive voltage: 3.3V/5V power supplyWorking temperature: -20 degree to +70 degreeStorage temperature: -30 degree to +80 degreeInterface definitionStandard 16X4 LCD character module1604 the standard 16 foot interface, which:First feet: VSS for ground powerSecond feet: VDD 5V positive power supplyThird feet: V0 is the contrast adjustment terminal of LCD, when the positive power supply is the weakest, the contrast is the highest when the grounding power is the highest. When the contrast is too high, it will generate ghosting. When using it, we can adjust the contrast through a 10K potentiometer.Fourth feet: RS is a register selection, the high power usually selects the data register, the low normal selection instruction register.Fifth feet: R/W is read and write signal line, high power normally read operation, low electricity usually write operation. When RS and RW work together for low power, they can write instructions or display addresses. When RS is low level, RW can read busy signals at high power. When RS is high level, RW can write data for low power.Sixth feet: the E end makes the end, when the E end from high level jump into low power, the LCD module executes the command.Seventh to 14 feet: D0 ~ D7 were 8 bi-directional data lines.Fifteenth feet: backlight power cathodeSixteenth feet: backlight power supply negative poleOur advantages:FactoryOEM supportedShort time deliveryFlexible paymentAftersale service guaranteeHardware&software technicians supported Technician: We treat every piece of our product as our kid.
