Description

The WEA012832K is a 2-inch graphic OLED display that combines an ultra-thin design with a high contrast ratio, making it an excellent choice for various applications. Featuring a COG structure with an integrated PCB, this module offers a resolution of 128x32 dots. It is equipped with the SSD1315 IC and supports a 4-wire SPI interface. The module operates at a logic supply voltage of 3.0V.

Thanks to OLED technology, the display achieves a contrast ratio of 10,000:1, ensuring crisp and vibrant visuals, even in challenging lighting conditions. Its slim and lightweight design makes it suitable for applications where space and weight are critical.

The WEA012832K module is designed to perform reliably across a wide temperature range, operating from -40℃ to +80℃, with storage temperatures ranging from -40℃ to +85℃. For customers who prefer a version without an integrated PCB, the WEO012832K model is available as an alternative.

This OLED display offers not only outstanding performance but also the versatility and durability required for demanding environments.

Interface Pin Function

No.	Symbol	Function
1	GND	Ground.
2	VCC	Power supply pin for core logic operation.
3	D0	The serial clock input
4	D1	The serial data input
5	RES#	This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin HIGH (i.e. connect to VDD) during normal operation.
6	D/C#	This pin is Data/Command control pin connecting to the MCU. When the pin is pulled HIGH, the data at D1 will be interpreted as data. When the pin is pulled LOW, the data at D1 will be transferred to a command register. In I2C mode, this pin acts as SA0 for slave address selection.
7	CS#	This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW (active LOW).
