WEO12832W#RP3N00000-FC

PMOLED 0.91" Graphic 128x32, White color, COG, 3V, Interface l2C (FPC per Soldering), SH1106 IC, Glare

DESCRIPTION

WEO12832W#RP3N00000#-FC is a popular 0.91-inch COG graphic OLED module in the market. This module features a resolution of 128x32 dots and integrates the SH1106 IC, supporting an I2C interface. The IC also facilitates internal power boost and external power supply. With outline dimensions of 30.0 × 11.5 mm and an active area of 22.384 × 5.584 mm, the module is very lightweight due to its COG structure, measuring just 1.26 mm in thickness.

The logic power supply voltage ranges from 1.65V to 3.3V, with a typical value of 3.0V, and operates with a duty cycle of 1/32. Additionally, the module features a wide temperature range, reliably operating from -40℃ to +80℃, with a storage temperature range of -40℃ to +85℃.

This module is particularly suitable for various applications requiring compact and lightweight OLED displays. It is ideal for integrating into devices such as voice recorder, charging cables with embedded OLED displays and keychain lights featuring OLED displays, where space and visual clarity are paramount.

Interface Pin Function

No.	Symbol	Function
1	C1N	Connect to charge pump capacitor. These pins are not used and should be disconnected when Vpp is supplied externally.
2	C1P
3	C2P
4	C2N
5	VDD2	Power supply pad for Power supply for charge pump circuit. This pin should be disconnected when VPP is supplied externally
6	NC	No connection
7	VSS	Ground.
8	VDD1	Power supply input
9	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.
10	SCL	When the I2C interface is selected, D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SDAI).
11	SDA
12	IREF	This is a segment current reference pad. A resistor should be connected between this pad and VSS. Set the current at 18.75uA.
13	VCOMH	This is a pad for the voltage output high level for common signals. A capacitor should be connected between this pad and VSS.
14	VPP	OLED panel power supply. Generated by internal charge pump. Connect to capacitor. It could be supplied externally.
