YOK154MGI-Q1 1.54inch OLED Module SSD1309 Display with 128x64 Resolution IIC Interface for STM32, C51,Arduino, Raspberry Pi and MSP430 platforms
Product Features
- 1.54 inch OLED screen with black and white or black and blue color display
- 128x64 resolution for clear display and high contrast
- Large viewing angle: greater than 160° (one screen with the largest viewing angle in the display)
- Wide voltage supply (3V~5V), compatible with 3.3V and 5V logic levels, no level shifting chip required
- With IIC bus, only a few IOs can be used to light up the display
- Ultra-low power consumption: normal display is only 0.06W (far below the TFT display)
- Military-grade process standards, long-term stable work
- Provides a rich sample program for STM32, C51, Arduino, Raspberry Pi and MSP430 platforms
- Provide underlying driver technical support

NOTE:
1. This module supports IIC slave device address switching (shown in red box in Picture 2), as follows:
A. Solder the 0x78 side resistance, disconnect the 0x7A side, then select the0x78 slave address (default);
B. Solder the 0x7A side resistance, disconnect the 0x78 side, then select the0x7A slave address;
2. The hardware switches the IIC from the set address, and the software also needs to be modified accordingly. For the specific modification method, see the following IIC slave device address modification instructions.
Hardware Configuration
The hardware circuit of this module is composed of five parts: OLED display control circuit, OLED boost circuit, IIC slave device address selection circuit, pin array interface, and power supply voltage stabilizing circuit.
OLED display control circuit is mainly used to control OLED display, including chipselection, reset, data and command transmission control.
The IIC slave address selection control circuit is used to select different slave addresses.
The OLED boosting circuit is used to boost an input voltage to an OLED light emitting voltage.
The pin array interface is used for external connection of the main control development board.
The power supply voltage stabilizing circuit is used for 3.3V voltage stabilizing power supply.
The OLED module adopts IIC communication mode, and the hardware is configured with two pins: SCL (IIC data pin) and SDA (IIC clock pin). The IIC data transmission can be completed by controlling these two pins according to the IIC working timing.
