Description

WEA012864D-01: 0.96" Industrial OLED Module with PCB (SSD1306)

The WEA012864D-01 is a 0.96-inch Graphic OLED display module with a 128x64 pixel resolution. Designed for industrial-grade reliability and interface flexibility, this model integrates the OLED panel onto a high-quality PCB, simplifying mechanical mounting and rapid prototyping.

Key Features & Advantages:

Dual Interface Support: Supports I2C (default) and SPI interfaces, providing more options for different controller requirements.
3V/5V Logic Compatibility: Built-in level conversion circuit allows direct connection to both 3V and 5V systems (such as Arduino or ESP32) without an external level shifter.
Robust Mechanical Design: The 38.0 x 28.5 mm PCB includes 4 pre-drilled mounting holes for secure installation in high-vibration environments.
Easy Integration: Equipped with an 8-pin metal header, making it easy to plug into breadboards or sockets.

Powered by the industry-standard SSD1306 IC, the WEA012864D-01 is highly suitable for smart controls, industrial heaters, medical devices, and handheld meters. It operates reliably within a wide temperature range of -40°C to +80°C.

Interface Pin Function

No.	Symbol	Function
1	SDA	When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 will be the serial data input: SDIN. When I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin in application and D0 is the serial clock input, SCL.
2	SCL
3	SA0	In I2C mode, this pin acts as SA0 for slave address selection. When 3-wire serial interface is selected, this pin must be connected to VSS.
4	RST	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.
5	CS	This pin is the chip select input. (active LOW).
6	VDD	3.0V Power supply pin for core logic operation.
7	VIN	5.0V Power supply pin for core logic operation.
8	GND	This is a ground pin.
