Features:No need backlight, the display unit can emit light.High resolution: 128 * 64 (same as the LCD12864, but this product's sharp is more intensive).Support a large number of control chip: fully compatible for Arduino, 51 series, MSP430 series, STM32 / CSR chip etc.Ultra low power consumption: the power is 0.08w when full-screen lighting, 0.06w when normal full-screen displays Chinese characters (far lower than TFT, LCD and other technologies).Wide voltage support: no need to modify, direct support 3V ~ 5V DC.Less occupancy of IO port: need 4 IO port (Max. ) to drive system when using SPI or IIC communication.No character library: take word through model software. Specifications:Visual angle: > 160 (almost at a plane)Wide voltage support: 3V ~ 5V DCOperating temperature: -40 ~ 70 Module volume (length and width): 27.3MM * 27.8MM * 3.7MM (slightly larger than a coin)Package Weight: 4gPackage List:1 x LCD Module.
