Module, Oled module
- resolution: 128X64
- super wide viewing angle: more than 160 ° (maximum viewing angle display a screen)
- ultra-low power consumption: normal display 0.08W (far below the TFT display)
- wide supply range: DC 3V-5V (without any changes, directly compatible with common 3.3V and 5V power supply system)
- industrial grade: Operating temperature range -30 degree~ 70 degree
- the ultra-small size: (length) 35.4MM * (W) 33.5MM * (thickness) 4.3MM
- support for multiple operating modes: 3-wire SPI, 4 wire SPI, IIC
- with chip select CS signal, you can achieve multiple SPI or IIC device on the same bus work
- compatible with 3.3V and 5V control chip I / O level (without any set, directly compatible)
- OLED screen, internal drive chip: SH1106 (Operation and SSD1306 same)
