Description:84 X 48 dot LCD,can show 4 lines of charactersUse serial interface communicate with the master processor,the number of interface signal line reduced greatly, only 8 signal lines including power and GND.Support different types of MCU,such as the SPI,MCS51 serial mode 0 of AVR.Transfer rate up to 4Mbps,can full speed write display data without waiting time.Can use the conductive glue to connect the module with the printed board,without connecting cable.The metal hooks on the module can fix the module on the printed board,which is very easy to install and replace.LCD controller/driver chip has been bound to LCD chip,the volume of LCD is small. Low power supply,the working current in normal situation is lower than 200μA,and has power-down mode.Specification:Power supply voltage: 2.7-3.3V,5V is OK, but part of the screen becomes black when testedData interface level: 2.7-5VBacklight power supply voltage: highest 3.3VInstallation diameter: 2mmBacklight: BlueRST--resetCE--chip selectionDC--data/commands choiceDIN--serial data lineCLK--serial Clock SpeedVCC--power supply 3.3VBL--backlight control terminalGND--power negativePackage Includes:1 Piece LCD Module2 Pieces Pin Header
