The diameter of the domestic P75-B nickel-plated needle is 1.02 mm, and the total length of the thimble needle is 16 mm.

Serial communication data transmission rate is typically expressed in bits per second (bps), which means the number of bits transferred every second. Baud is a unit used to measure the baud rate, which refers to the number of signal changes per second on a communication channel. In other words, it's the frequency at which electrical signals are sent over the communication line. While baud is an electrical measurement, it doesn't always directly equate to the actual data transfer rate. When each data bit is encoded within a single signal cycle, bps and baud rate are equal. However, if encoding or compression algorithms are used, the bit transfer rate can exceed the basic baud rate. A UART (Universal Asynchronous Receiver/Transmitter) only handles the physical transmission and reception of electrical signals. Therefore, when setting up a UART serial port on a microcontroller or microcomputer, the baud rate is usually set as the unit of measurement. On the other hand, the actual data transfer rate on the data line should be measured in b/s, especially since modems often use advanced encoding techniques to boost the transmission speed. Understanding the difference between these two units is essential for optimizing communication systems and ensuring accurate data exchange.
