Product Descriptions
Equipped with a 0.96oled128 * 32 display, the prototype of the development board is Arduino Nano. When downloading, select the Arduino Nano module to test that the program has been written into the firmware. After receiving it, plug it in and connect it to a computer via USB. The serial chip is CH340. The IIC communication pin of OLED is the module's SDA=A4, SCL=A5, and the IIC address of OLED is 0X3C The screen driver program resources are abundant, and you can directly search for Arduino 0.91 OLED on the website to find it.
This product has three versions: the USB interface is different, but the functions are the same.
HW-441A Mini UsB interface
HW-441B Micro UsB interface
HW-441C Type-C USB interface
