Power supply voltage: 2.7V- 3.3V Backlight Power Supply Voltage: 3.3V MAX 43.6mm x 43.1mm(width X height) 84 x 84 dot matrix LCD,can show 4 lines of characters, 12 Characters Per Line
Uses Serial Peripheral Interface (SPI) to communicate with the microcontroller, only 8 signal lines including power and GND. Support different types of MCU (MicroController Unit) , such as Arduino, PICAXE, ARM, Raspberry PI etc. Transfer rate up to 4Mbps,can full speed write display data without waiting time. LCD controller/driver chip has been bound to LCD chip so the overall footprint of the LCD Module is Kept as small as possible. Has TWO Rows where header pins can be soldered for greater flexibility of use! Low power supply, the working current in normal situation is lower than 200μA,and has power-down mode.
