Project Development Background The construction of the track inspection robot is realized through an intelligent track inspection robot based on 5G communication technology, equipped with data collectors and real-time intelligent analysis software, to achieve gas and combustible gas detection, and eliminate safety hazards alarms. It creates a standardized, modernized, and intelligent security inspection program. It … Read more
I am Lao Wen, an embedded engineer who loves learning. Follow me to become better together! An architectural pattern is a general reusable solution to a commonly occurring problem within a given context in software architecture. A pattern is a solution to a problem in a specific context. However, many developers still struggle to understand … Read more
When transitioning from concept to product, selecting a power supply is essential. An isolated power module provides 12V power for advanced ASICs, microcontrollers, FPGAs, and various other components. As always, these components practically fill the space on the circuit board, providing sufficient power, stability, thermal performance, low noise, and reliability, which challenge the laws of … Read more
CSI + DVP camera design principle is simple, understand it yourself. PDN_TX: Different modules have different effective levels, please pay attention. ID_TX: ID_TX is the camera address, not the motor address, and the internal pull-up and pull-down resistors corresponding to ID_TX have different camera addresses. Please let the software driver engineer pay attention. RC / … Read more
Today, a letter arrived from Stanford University, containing a card with a single sentence:“I am an engineer. The way I serve humanity is by making dreams come true.” The origin of this quote is unknown, but coincidentally, someone we recently interviewed said almost the same thing. Perhaps this is a common “belief” among engineers. The … Read more
New course on FPGA practical training: schematic – PCB – board fabrication – debugging – code validation. 1) The course provides detailed explanations of schematic design and PCB layout wiring rules, writing detailed project design specifications, and understanding how to design each signal. 2) Core board + baseboard architecture; convenient for students to quickly apply … Read more
In hardware design, PCB design is a very important and indispensable step. For some simple products, PCB design may simply involve connecting all components and networks accordingly. However, for high-speed circuits and RF circuits, the design of the PCB directly affects whether the product functions properly and whether it meets market requirements. Below, I will … Read more
Remember when I first did PCB Layout, multi-layer board prototyping costs were very high, and the delivery time was about seven or eight days. Due to cost and time considerations, I often only considered using double-sided boards for routing. Then, holding many design rules that would often “conflict” with each other or experience-based rules circulating … Read more
