REA012832P - Graphic OLED Display Module - Raystar

1.71-inch 128×32 COG+PCB Graphic OLED Display Module (CH1115 IC)

Model No. REA012832P

REA012832P is 1.71-inch graphic COG OLED display with PCB. This resolution of this display is 128x32 pixels. This OLED module has built-in IC CH1115 supporting 4-Wire SPI interface. I/F provides a standard PIN (2.54mm pinhole) row to facilitate customers to connect the module with their applications. The boost circuit is equipped on the PCB board, so customers can simply provide a set of VDD voltage to use the module.

The PCB board's screw-hole design allows customers to mount the module easily. High contrast ratio 10,000:1 making the visual performance stand out from traditional displays. Logic supply voltage ranges from 2.5V-3.3V; typical value is 3V. The module works within temperature from -40℃ to +80℃; Storage temperature range is -40℃ to +85℃.

Pin No.	Symbol	Function
1	GND	Ground.
2	VCC	Power supply pin for logic.
3	D0	When the serial interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SI).
4	D1
5	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.
6	D/C#	This is the Data/Command control pad that determines whether the data bits are data or a command. D/C = “H”: the inputs at D0 and D1 are treated as display data. D/C = “L”: the inputs at D0 and D1 are transferred to the command registers.
7	CS#	This pad is the chip select input. When CS# = “L”, then the chip select becomes active, and data/command I/O is enabled.
