Features:This is a 0.96 inches OLED display module of 128X64 resolution in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. Working without backlight, the OLED display module could give out light by itself. In low ambient light conditions such as a dark room, an OLED screen can achieve a higher contrast ratio than an LCD. OLED display module also has a much faster response time than an LCD. The display with small dimension is suitable for MP3, function cellphone, smart health device, etc. Specification:Text Color: Blue, White, Blue+Yellow (Optional)Display Size: 0.96in Resolution: 128*64Interface Type: IIC (only has two I/O port) View Angle: >160 Supported Platform: For 51, MSP430, STIM32 / 2, SCR chipLow Power Consumption: 0.04W (normal operation)Voltage: 3.3V-5V DC Operating Temperature: -30~80 Size: 27*27mm / 1.1*1.1inWeight: 9g / 0.3oz (approx.)Interface:VCC: 3.3-5VGND: GroundSCL: Serial ClockSDA: Serial DataPackage List:1 x OLED Display Module
