Some may have noticed that the voltage standards for microcontrollers vary; some operate at 3.3V while others use 5V. Why isn’t there a unified standard? Is this a historical legacy issue or an inevitable result of technological evolution? Today, we will explore this question. 1. The Aftermath of the TTL and CMOS ‘Cold War’ The … Read more

The security industry is an important sector driven by the safety needs of modern society. With continuous technological advancements, video surveillance technology has evolved from “seeing” to “seeing far,” “seeing clearly,” and finally to “understanding,” pushing the industry from analog surveillance to digital surveillance, network high-definition surveillance, and ultimately into the era of intelligent surveillance. … Read more
Recently, many friends have inquired about CIS-related information. I plan to use this as the theme for this week, concentrating on updating 3 to 5 articles. Today is the first article, starting with an introduction to CIS to help everyone understand its fundamental concepts.The CMOS Image Sensor (CIS) is a semiconductor device based on Complementary … Read more
To see the virtuous and aspire to be like them, to see the unvirtuous and reflect on oneself. —The Analects of Confucius, Chapter on Benevolence The security industry is an important sector born from the modern society’s demand for safety. With continuous technological advancements, video surveillance technology has evolved from “seeing” to “seeing far,” “seeing … Read more
A camera module is a functional module that integrates components such as an image sensor, lens, and signal processing circuits, used to capture and process image or video information. It is widely used in various fields such as smart homes, intelligent transportation, smart agriculture, and security monitoring. Below is a detailed introduction to its working … Read more
Click the blue text to follow us Recently, a group of researchers from Cornell University successfully installed a ‘brain’ on a solar-powered smart microbot. These microbots range in size from 100 to 250 micrometers — almost the width of a human hair. Robots of this size are typically externally controlled, but the prototype from Cornell … Read more
OVM6211 – Eye-Tracking Camera Features Recently, I noticed that the VGA timing feels quite similar to modern MIPI. This timing or data transmission is really interesting. We see a large CMOS, with various types of optoelectronic PN junctions that I have discussed before. Transimpedance amplifier design reference. Photodiode parameters like this. Since we are reading … Read more
1 Introduction The previous article reviewed the hierarchical methods of low power design【Technical Review】, and this article further discusses some of the key points. This is particularly beneficial for those who are new to low power design, as it may provoke more thoughts. 2 Why Low Power Design is Necessary The previous article mentioned several … Read more
