characteristics:

84X84 dot matrix LCD, can show 4 lines of characters

Use interface series interface with the master processor, the number of line interface interface significantly reduces, only 8 lines of signals, including power and GND. Support various types of MCU, such as the SPI, MCS51 series mode 0 from AVR. Transfer rate up to 4 Mbps, can full speed write data display without waiting time.

Can use the conductive glue to connect the module with the printed board, without cable connection. The metal hooks on the module can fix the module on the printed circuit board, which is very easy to install and replace.

LCD controller / driver chip has been linked to LCD chip, LCD volume is small

Low power, the operating current in normal situation is lower than 200μA, and has power-down mode
