1. Function USB network serial port LCD display
2. Performance, power consumption, and speed
3. Price
4. Operating System Support
5. familiarity and development resources
6. stable supply of General chips for large manufacturers

Since data encrypted with too short keys can be parsed to break the captured traffic, both devices should be set up to use a 128-bit key. (Computer science)
Further steps to make the most of these built-in Bluetooth measures include:
• Turn off the Bluetooth interface and turn off the discovery feature of Bluetooth. This feature allows

You may often encounter the function of generating thumbnails when creating a website, because thumbnails of different sizes may be used in different situations.
The image generated in this article is square. Only the thumbnail of the square ensures that the image is clear enough.
When the square I mentioned here is first compressed proportionally, then a fixed white background is added and then displayed in the center.
