Produino 2.42” OLED White Screen 128×64 SSD1309 SPI IIC Serial 7Pin for Arduino STM32 MCU TP

This is a 2.42 inch OLED display module of 128×64 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.
The seventh pin CS signal is leaded by default; If you do not need it, you can solder R18, then CS signal is directly grounded.
You can use SPI or IIC, and the default interface is SPI(R17 is soldered, R15, R13 are not soldered); change interface by soldering or desoldering R15, R17, R13(SPI: R17, IIC: R15, R13)
