RK3588 and RK3588S Cost Price: Differences in Cost-Effectiveness RK3588S, as an optimized version of RK3588, has advantages in cost control. If the project is cost-sensitive and does not require high-performance interfaces, RK3588S can meet basic needs with a more economical solution; while RK3588, with its more comprehensive configuration and richer interfaces, is suitable for scenarios … Read more
On the RK3588 platform, after a certain stage, if the hardware cursor is enabled, it is likely to disappear in some scenarios, and cannot be restored without a system reboot. Based on this phenomenon, it can be determined that the root cause lies within the kernel. Below, we will discuss this issue and how to … Read more
For the layout of SMT components with small pin pitches such as QFP, QFN, and SOP, we sometimes encounter situations where adjacent pins of these components need to be interconnected. It has been observed that many designers, in an effort to save time, directly route the connection between the pads, effectively shorting the pins together. … Read more
Question: In PCB routing, there are three common types of bends: right angle, 45 degrees, and arc (as shown in the figure below). Which type of bend is the best? This question can be answered relatively easily based on experience, with most people agreeing that arc > double 45 degrees > right angle. However, empirical … Read more
Introduction:Everyone knows that impedance should be continuous. However, as Luo Yonghao said, “In life, there are always times when you step in something unpleasant,” PCB design also has its moments of impedance discontinuity. What should we do? Characteristic Impedance Characteristic Impedance: Also known as “Feature Impedance”, it is not a DC resistance, but a concept … Read more
