0.49 Inch OLED Display 64*32 Dots Product Introduction
0.49-inch OLED products are small display screens widely used in
various smart devices and instruments due to their ultra-thin,
low-power, high contrast, and wide viewing angle characteristics. A
0.49-inch OLED display typically has a 64x32 pixel dot matrix,
capable of displaying white fonts, driven by an SSD1315 controller,
supports I2C serial interface, and operates at 2.8V voltage. This
type of display screen, due to the self luminous characteristics of
OLED, does not require backlighting, thus having the advantages of
ultra-thin body design and low power consumption. Their working
temperature range is wide, from -40 ℃ to 85 ℃, and they are
suitable for various environmental conditions. In addition, the
0.49-inch OLED display screen adopts FPC connection method, which
facilitates direct soldering to the PCB without the need for
connectors.
0.49-inch OLED products are highly suitable for devices with strict
space requirements due to their compact size and high resolution.
They are widely used in smart watches, health monitoring devices,
small display screens for industrial control systems, portable game
consoles, and other occasions that require small and efficient
display screens. 0.49-inch OLED products have become one of the
preferred solutions for modern small displays due to their unique
technological advantages and wide application potential. With the
maturity of technology and the expansion of the market, we can
expect such products to play a more important role in future smart
and electronic devices.

Interface Pin Definition
| Pin No. | Symbol | I/O | Function |
| PowerSupply |
| 8 | VDD | P | Power Supply for Logic
This is a voltage supply pin. It must be connected to external
source. |
| 7 | VSS | P | Ground of Logic Circuit
This is a ground pin. It acts as a reference for the logic pins. It
must be connected to external ground. |
| 14 | VCC | P | Power Supply for OEL Panel
This is the most positive voltage supply pin of the chip. A
stabilization capacitor should be connected between this pin and
VSS when the converter is used. It must be connected to external
source when the converter is not used. |
| Driver |
| 12 | IREF | I | Current Reference for Brightness Adjustment
This pin is segment current reference pin. A resistor should
between this pin and VSS. Set the current at 12.5μA maximum. |
| 13 | VCOMH | O | Voltage Output High Level for COM Signal. This pin is the input pin
for the voltage output high level for COM signals. A
capacitor should be connected between this pin and VSS. |

| Power Reset for Controller and Driver
This pin is reset signal input. When the pin is low, initialization
of the chip is executed. Keep this pin pull high during normal
operation. |
| 10 | SCL | I | I2C Bus Data Signal
The transmission if information in the I2C bus is following a clock
sigmal. Each transmission of data bit is taken place during a
single clock period of this pin. |
| 11 | SDA | I/O | I2C Bus Data Signal
This pin acts as a communication channel between the transmitter
and the receiver. |
