PMOLED 0.91" Graphic 128x32, White color, COG, 3V, Interface SPI,I2C (FPC per Zif), CH1120 IC, Glare

DESCRIPTION

The WEO12832W#SP3N00000-FC is a 0.91-inch OLED display module with a 128x32 dot matrix and integrated CH1120 driver IC. Designed for compact systems, this OLED 0.91-inch display is optimized for applications where mechanical depth, power efficiency, and clear monochrome rendering are key constraints. It supports 4-bit grayscale, offering more flexibility for UI expression compared to traditional 1-bit OLED modules.

The OLED display 0.91 128x32 operates at 3V logic power and offers SPI and I2C interfaces for seamless integration with most MCU platforms. The module features a wide viewing angle of 160° (H/V) and an extensive operating temperature range from –40°C to +80°C, ensuring stable performance in both consumer and industrial environments.

1 ESD_GND This pin should be connected to GND.
2 VPP OLED panel power supply.
Connect to capacitor. It could be supplied externally. This is the most positive voltage supply.
3 VCOMH This is a pin for the voltage output high level for common signals.
A capacitor should be connected between this pin and VSS.
4 SEGH This is a segment pre-charge voltage.
A capacitor can be connected between this pin and GND if necessary. When external capacitor is not used, this pin should be kept NC.
5 VSL Discharge voltage level pad.
This pad should be connected to resistor and diode externally.
6 VSS Ground for logic and analog. This pin should be connected to GND externally.
7 VDD Power supply for logic.
8 RES This is a reset signal input pin. When RES is set to “L”, the settings are initialized. The reset operation is performed by the RES signal level.
This pin internal pull high.
9 A0/SA0 This is the Data/Command control pin 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.
10 CS This pin is the chip select input. When CS = “L”, then the chip select becomes active, and data/command I/O is enabled.
