In the vast realm of embedded systems, both STM32 and GD32 are prominent 32-bit general-purpose microcontrollers, with applications spanning industrial control, smart homes, consumer electronics, and more. For engineers and developers, understanding the differences between them is crucial for making the right choice in projects. Next, we will analyze the differences between these two chips … Read more
In the design of BLE HID (Bluetooth Low Energy Human Interface Device) devices, power consumption is a critical technical indicator, especially for battery-powered devices such as wireless keyboards, mice, remote controls, headphone controllers, and game controllers. A good BLE HID design typically requires long standby time, quick wake-up, efficient transmission, and extremely low power consumption. … Read more
LVR, which stands for Low Voltage Reset, is a circuit protection mechanism that allows a system to automatically reset when the power supply drops below a specific threshold. This helps prevent unpredictable errors or damage to the system under low voltage conditions, ensuring system stability and improving reliability.Taking the PMS152G as an example, we can … Read more
In today’s world where smart devices are ubiquitous, IoT SIM cards are quietly changing our way of life. As the “invisible bridge” connecting everything, they free devices from the constraints of Wi-Fi, but also expose some issues worth considering in practical applications. The Duality of Freedom and ConstraintThe most significant advantage of IoT SIM cards … Read more
Although BLE HID (Bluetooth Low Energy Human Interface Device) has a simple structure and low power consumption during development, it often encounters tricky issues due to challenges in cross-platform compatibility, security certification, and connection stability. Below are common problems and corresponding solutions applicable to scenarios involving the development of BLE HID keyboards, mice, remote controls, … Read more
A few years ago, we worked on an IoT project using the STM32 solution, where the client insisted that the coin cell battery must last for five years. We were familiar with this task. We entered the <span>Standby</span> mode, turned off everything that could be turned off, and measured the current with a multimeter in … Read more
The second generation 8nm high-performance AIoT platform from Rockchip, the RK3576 family, has a new member – RK3576S. To summarize: compared to the main model,RK3576/RK3576J, the performanceis slightly reduced, while the power consumption has decreased. It is mainly used in commercial AIoT fields such as commercial display terminals, smart home appliances, robots, and the Internet … Read more
Developers of smart home devices are closely monitoring the foundational technologies of the new generation Zigbee 3.0 wireless standard, from gateways to hardware development. The perfect application of this technology in smart lighting, door locks, thermostats, and other home automation devices has sparked lively discussions. This article compiles ten common questions and answers regarding the … Read more
It’s already 2024, and I believe everyone is familiar with solid-state drives (SSDs). With continuous technological updates, the interface speed of SSDs has now reached PCI-e 5.0.This isn’t exactly new technology; Micron launched the world’s first PCI-e 5.0 SSD, the Crucial T700, back in May 2023. It uses the Phison E26+ controller with its own … Read more
