# SSD1306 OLED Display (Deprecated)

> Monochrome 128x64 OLED display with I2C interface

Monochrome 128x64 OLED display with I2C interface

<Warning>
  This part has been deprecated. Please use [board-ssd1306](./board-ssd1306) instead.
</Warning>

## Pin names

<ParamField path="DATA" type="pin">
  I2C data line (SDA) - Arduino Uno pin A4
</ParamField>

<ParamField path="CLK" type="pin">
  I2C clock line (SCL) - Arduino Uno pin A5
</ParamField>

<ParamField path="DC" type="pin">
  Unused (for SPI mode, not supported)
</ParamField>

<ParamField path="RST" type="pin">
  Unused (for SPI mode, not supported)
</ParamField>

<ParamField path="CS" type="pin">
  Unused (for SPI mode, not supported)
</ParamField>

<ParamField path="3V3" type="pin">
  3.3V regulated output
</ParamField>

<ParamField path="GND" type="pin">
  Ground
</ParamField>

<ParamField path="VIN" type="pin">
  Supply voltage
</ParamField>

<Note>
  DC, RST and CS are for SPI mode. The SSD1306 simulation only supports I2C mode, so these pins are not functional.
</Note>

The default I2C address of the SSD1306 module is 0x3c (60).

## Attributes

<ParamField path="i2cAddress" type="string" default="0x3c">
  I2C address of the display
</ParamField>

## Simulator examples
