These tiny 0.9 inch uOLED displays have a resolution of 128 x 32 pixels and use a standard serial I2C interface (address = 0x3C) for communication. Based on the SSD1306 controller, the module is available in both white and blue pixel colours. By making use of OLED screen technology these displays are self illuminated and therefore require no back light. When compared to standard LCD and TFT technology they have significantly less power consumption and a significantly clearer display. If using with an Arduino board they are also compatible with our own HCOLED graphic library (see http://forum.hobbycomponents.com/viewto ... =58&t=1817)
Product code: HCMODU0118 (white) HCMODU0119 (blue)
Module size: 38 x 12mm
High pixel density
Resolution: 128 x 32
Ultra-low power consumption: normal display 0.06W (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 C ~ 70 C
5V tolerant interface.
OLED screen, internal drive chip: SSD1306
1....GND: Power ground
2....VCC: 3.3V or 5V power supply
3....SCL: I2C Clock
4....SDA: I2C Data
