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 DC Operating temperature: -40 ℃ ~ 70 ℃ Module volume (length and width): 27.3MM * 27.8MM * 3.7MM (slightly larger than a coin) Package Weight: 4g Package List: 1 x LCD Module .
