1.Parameters1>.Power supply voltage:2.7V-3.3V2>.Data interface level:2.7-3.3V3>.Backlight power supply voltage:highest 3.3V4>.Module size:43.6mm x 43.1mm(width X height)5>.Installation diameter:2mm

2.Connection1>.RST--------- reset2>.CE---------- chip selection3>.DC---------- data/commands choice4>.DIN--------- serial data line5>.CLK--------- serial Clock Speed6>.3.3V-------- VCC7>.LIGHT------- backlight control terminal8>.GND--------- power negative

3.Features:1>. 84 X 84 dot matrix LCD,can show 4 lines of characters2>. Use 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 arduino,AVR,PIC,STM32,STC MSP430 and so on.Transfer rate up to 4Mbps,can full speed write display data without waiting time.3>. 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.4>. LCD controller/driver chip has been bound to LCD chip,the volume of LCD is small5>. Low power supply,the working current in normal situation is lower than 200μA,and has power-down mode
