The main purpose: It can be used for 2B/3B/3B+/4B full range of development boards, for , C51, STM32 and other platforms. The provides programs that can display CPU, temperature, memory, hard disk occupation, IP address and other information. The OLED screen pin header has been soldered, and the finished line is optional, which can be directly connected to the for . High resolution: 128x64 (same resolution as 12864, high ); Viewing angle: 160 Power consumption: normal display 0.06w (far lower than TFT display) Wide voltage power supply (3V-5V), compatible with 3.3V and 5V level logic, without level conversion chip IIC interface only needs 2 IO to light up easily. Working temperature range is industrial grade (-20-70); -grade process standards, long-term stable work. Instructions for use: 1. Correct wiring Pins on the module for GPIO VCC 5V/3V (red wire) GND GND (black wire) SCL SCL (yellow line) SDA SDA (blue line) 2. Install the WinSCP tool on the computer, connect to the for and download the data to the home/pi directory of the for . 3. Compile the program file gcc -o oled oled.c ssd1306_i2c.c -lwiringPi Among them, the gcc compiler is called, -o means the generated file, followed by the generated file name, oled.c and ssd1306_i2c.c are programs, and -lwiringPi refers to the wiringPi library of the . 4. Run the program ./oled At this point, you can see the CPU occupancy rate, CPU temperature, running memory occupancy rate, disk occupancy rate and IP address of the displayed on the oled screen. Due to different batches, there may be differences in product appearance, color, and printed text, which not affect the use. Colour:Random Color(The color is random, and the designation is not accepted) Material:PCB Package Contents: 1 x 0.96 inch OLED Display Kit Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
