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: 160Power 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 chipIIC 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 wiringPins on the module for GPIOVCC 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 filegcc -o oled oled.c ssd1306_i2c.c -lwiringPiAmong 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./oledAt 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:PCBPackage Contents:1 x 0.96 inch OLED Display KitOnly 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.
