Intelligent Character OLED

OLED displays are vibrant, easy to read, and power concious.  Control of these intelligent OLED modules has been simplified to a set of commands delivered via RS232, RS422, I2C and USB. Meant to save time and money, we have worked to ensure that the tedious timing and special conditions typical of display controllers have been eliminated from our interface to help get your project to market faster.

  • Colours

    OB OLED Blue on Black

    OG OLED Green on Black

    OR OLED Red on Black

    OW OLED White on Black

    OL OLED Yellow on Black

  • Voltage/Temperature

    E  Extended Temperature (-20C to 70C Operation)

    V  Wide Voltage (9V-15V)

    VPT  Wide Voltage with Efficient Switching Power Supply (9V-35V)

  • Interfaces

    I2C  Inter-integrated circuit protocol uses clock and data lines to communicate short distances at slow speeds from a master to up to 128 addressable slave devices. A display is a slave device.

    RS232  Recommended standard 232, a common serial protocol. Logic levels can be as high as +/-30V, a high level is negative, a low is positive.

    RS422  Recommended standard 422, a more robust differential pair serial protocol.

    TTL  Transistor-transistor logic applied to serial protocol. Low level is 0V while high logic is 5V.

    USB  Universal Serial Bus protocol widely used in PCs.

  • Features

    Dallas One-Wire  One Wire interface for connecting devices using Dallas Semiconductor protocol, such as the DS18S20 temperature probe.

    GPO  General Purpose Outputs for switching external circuitry and devices.

    Keypad  Matrix style keypad input.
