What? A calculator can run ChatGPT now? There is a video as proof; the program not only answered the author’s questions but also gave the classic ChatGPT response—42—when asked about “the meaning of life”. Moreover, it looks just like an ordinary calculator; the secret lies within the machine. Of course, the difficulty is not small. … Read more
4 Tips for Self-Learning FPGA FPGA is a highly integrated chip, and its learning process requires both programming skills and an understanding of hardware circuits and computer architecture. The knowledge and foundations involved are extensive, such as digital circuit fundamentals, EDA principles, Verilog/VHDL programming languages, FPGA algorithm design, FPGA simulation analysis, and PCB hardware design. … Read more
1. Introduction The previously made test circuit board for the STM32F373 did not have the 16-bit high-precision ADC pins exposed, so a new board was made to test the performance of the 16-bit ADC in the F373. 2. Designing the Circuit Board Based on the previous experimental circuit board, the original output pin header was … Read more
Friends who have worked with microcontroller products know that the STM32 chip has multiple VDD and VSS pins, as shown in the figure below: So why are there so many pins? Wouldn’t it be better to have fewer? Fewer pins make PCB routing easier. Actually, there are reasons for the chip being designed this way. … Read more
Abstract: Embedded hardware design is a systematic task. For engineers, understanding the processes and general methods involved is significant for carrying out their work. Today, let’s briefly discuss the general process in hardware design. 1. Requirement Analysis Requirement Analysis involves working with clients to analyze requirements and determine the final needs, establishing guiding documents such … Read more
Click Blue Text Follow us~ Multi-layer PCBs serve as the “core strength” in fields such as communications, medical, industrial control, security, automotive, power, aviation, military, and computer peripherals. As the product functions increase and the circuitry becomes denser, the production difficulty also rises. Currently, the domestic PCB manufacturers capable of mass-producing high multi-layer boards are … Read more
PCB Network News On many circuit boards or electronic products, we often see the following symbols. Do you know what they mean? FCC mark, CE mark, hand symbol, and trash can symbol on Atmel development boards RoHS mark and RU mark on NXP development boards Hand symbol, trash can symbol, and Pb mark on NXP … Read more
MAKER: mosivers／Translator: Qun Endless Thermochromic liquid crystal film is a fascinating material that changes color with temperature variations. DIYing a clock with this material makes the display and the changing process particularly unique! The clock uses a four-digit seven-segment display, with hours and minutes arranged vertically and slightly offset. Each part contains a controller PCB … Read more
Background:Some customers have reported that certain Hisense motherboards using H26M62002JPR, H26M51002KPR eMMC chips prompt a timeout error during reading, preventing read/write operations. The analysis indicates that the issue is due to non-standard eMMC. Hardware Support:This version is compatible with previous ones; simply transfer the socket head and 25 chips to the new PCB. Software Support:Versions … Read more
In high-speed circuit boards, eMMC is one of the most common and critical components, so properly routing eMMC is essential for the stable operation of the system! This article only focuses on PCB routing and does not involve schematic design! 1: Layout (1) Place the eMMC close to the main controller, ideally within 2000 mil. … Read more
