Model No. REP012832N

REP012832N is a 128x32 COG Graphic OLED Module. The diagonal size of the active area is 2.23 inches, and the module dimensions are 66.5x35.0 mm. The OLED module has a built-in SH1106 controller and supports 6800, 8080, 4-Wire SPI, and I2C interfaces, and provides a standard row of pins (2.54 mm pin hole). It also has a boost circuit designed on the PCB board, requiring customers only to provide a set of VDD voltages to use it. A new screw hole is added to the PCB board to facilitate module fixation, greatly improving the convenience for customers connecting the module to their products.

The REP012832 module supply voltage for logic is 2.9V to 3.5V, with a typical value of 3.3V. The available emitting colors are white and yellow. The OLED module has a high contrast ratio of 10,000:1. It can operate within a temperature range of -40℃ to +80℃, and its storage temperature ranges from -40℃ to +85℃.

1 VSS Ground.
2 VDD Power supply input.
3 NC No connection.
4 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 DB0 to DB7 are treated as display data.
D/C = “L”: the inputs at DB0 to DB7 are transferred to the command registers.
In I2C interface, this pad serves as SA0 to distinguish the different address of OLED driver.
5 R/W# This is a MPU interface input pad.
When connected to an 8080 MPU, this is active LOW. This pad connects to the 8080 MPU WR signal. The signals on the data bus are latched at the rising edge of the WR signal.
When connected to a 6800 Series MPU: This is the read/write control signal input terminal.
When R/W = “H”: Read.
When R/W = “L”: Write.
6 E/RD# This is a MPU interface input pad.
When connected to an 8080 series MPU, it is active LOW. This pad is connected to the RD signal of the 8080 series MPU, and the data bus is in an output status when this signal is “L”.
When connected to a 6800 series MPU, this is active HIGH. This is used as an enable clock input of the 6800 series MPU.
When RD = “H”: Enable.
When RD = “L”: Disable.
7~14 DB0~DB7 This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus.
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). At this time, D2 to D7 are set to high impedance.
When the I2C interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SDAI). At this time, D2 to D7 are set to high impedance.
15 CS# This pad is the chip select input. When CS = “L”, then the chip select becomes active, and data/command I/O is enabled.
16 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.
17 BS1 These are the MPU interface mode select pads.
