Features 1、No need backlight, the display unit can emit light. 2、High resolution: 128 * 64 (same as the LCD12864, but this product's sharp is more intensive). 3、Support a large number of control chip: fully compatible for Arduino, 51 series, MSP430 series, STM32 /, CSR chip etc. 4、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). 5、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. Specification Features: No need backlight, the display unit can emit light.
