Description

WEO012832P is a 1.71-inch COG small OLED display module that is made of 128x32 dots. This module is built in with CH1115 IC; it supports I2C and SPI interface, 3V power supply, 1/32 driving duty, the supply voltage of logic is 3.0V (VDD), and the current with 50% checkerboard display is 5mA @ 12V VCC (for white color). The WEO012832P model is an IC alternative solution to the WEO012832G model; the mechanical size and PFC pin definition are the same. For more details, please check the datasheet.

The WEO012832P is a COG structure OLED display that is ultra-thin and has no need for backlight; it's lightweight and has low power consumption. This 1.71-inch small OLED module is suitable for smart home applications, portable devices, health devices, testing instruments, etc. WEO012832P can be operated at temperatures from -40℃ to +80℃; its storage temperatures range from -40℃ to +85℃.

Interface Pin Function

No. Symbol Function
1 ESD_GND ESD Ground pin
2 VPP OLED panel power supply.
3 VSS This is a ground pin.
4 VSS This is a ground pin.
5 VDD Power Supply for Logic
6 __
CS
This pad is the chip select input. When /CS = “L”, then the chip select becomes active, and data/command I/O is enabled.
7 ___
RES
This is a reset signal input pad. When /RES is set to “L”, the settings are initialized. The reset operation is performed by the /RES signal level.
8 A0 This is the Data/Command control pad that determines whether the data bits are data or a command.
In I2C interface, this pad serves as SA0 to distinguish the different address of OLED driver.
9 SCL The serial clock input pad
10 SI/SDA The serial data input pad
11 NC Dummy Pin
12 IREF This is a segment current reference pad. A resistor should be connected between this pad and VSS. Set the current at 18.75μA.
13 VCOMH The pin is for COM signal deselected voltage level.
A capacitor should be connected between this pin and VSS.
14 VPP OLED panel power supply.
