RF engineers should better understand applications outside their industry, because it is not your competitors that will disrupt you, but possibly AI. Imagine a day when a large AI model starts to excel in RF design, capable of simulating, debugging, and testing by itself… Then RF engineers will truly be overwhelmed; we can work 996, … Read more
01 HC-12 Communication Module 1. Introduction These are two HC-12 wireless communication modules just assembled. The LED can display the number of bytes received. Now let’s go outside to the square to check the communication distance. Its communication baud rate is 9600, let’s see what the corresponding communication distance is in this case. 2. Measurement … Read more
Wireless remote control modules are widely used in remote switches, vehicle unlocking, garage door control, access control systems, and other fields. A set of remote control receiving devices consists of a transmitting part and a receiving part. The transmitter encodes the control button pressed by the user into a radio frequency signal and then transmits … Read more
315M Transmission Circuit Principles In a static state, 12V provides voltage to the collector of Q2 through L1, R1, and the base-emitter of Q1. When data arrives, Q2 turns on, causing the emitter of Q1 to be at 0 potential, which means Q1 is initially off. When the emitter of Q1 is at 0 potential, … Read more
We are making daily toothbrushes more convenient in a new way. With the increasing richness of people’s material lives, the proportion of food in daily social life is also rising, and various oral care issues are becoming more prevalent. The first step in oral care is “brushing teeth”. So, how do we choose a toothbrush? … Read more
