2.44 cm (0.96 inch) 128×64 OLED Display Module – SPI/I2C – 7 Pin

2.4 cm (0.96 inch) 128×64 OLED Display Module-SPI/I2C (7 Pin)

2.4 cm (0.96″) OLED Display Module is a precise small, OLED module that can be interfaced with any microcontroller using SPI protocol. It is having a resolution of 128×64. The package includes a display board, a display, 7 pin male header.  An organic light-emitting diode (OLED or Organic LED), also known as an organic EL (organic electroluminescent) diode, is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. This organic layer is situated between two electrodes; typically, at least one of these electrodes is transparent. Featured by Smartiphi OLEDs are used to create digital displays in devices such as television screens, computer monitors, portable systems such as smartphones, handheld game consoles, and PDAs. A major area of research is the development of white OLED devices for use in solid-state lighting applications.

Setting up SPI/I2C Connection with GMS096A OLED Module :

Being a new entry into the market, only limited resources are available on this small piece of a miracle (GMS096A). I2C/SPI configuration always demands helpful resources as in any case. For the SPI setup, the module comes in 4 wire SPI configurations by default, and to make it work with the Arduino you can use these libraries from Adafruit.

For the I2C setup, it demands a little bit of work on the module, let us start with resoldering the resistor from position R3 to R1 and then short the R8 resistor with some soldering tin (0 Ohm resistor). The R6 and R7 pullup resistors are already soldered, with nothing to do there. Once done, the module is ready for I2C communication! The CS Pin is not necessarily needed, so just connect it to GND. The DC Pin selects the address. For standard address wire it to GND. The RES-pin needs a low pulse at startup and a high voltage during operation (as in SPI mode), a 100nF capacitor to GND, and a 10k resistor to VCC would be ideal!
