The main purpose: It can be used compatible with2B/3B/3B+/4B full range of development boards, compatible with, 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 compatible with. 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 compatible withuse: 1. Correct wiring Pins on the module compatible withGPIO 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 compatible withand download the data to the home/pi directory of the compatible with. 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.
