As one of the representatives of intelligent wearable products, smart watches pay more attention to the appearance of the product itself, and also take into account the effect of users' wearing. So I think the screen of smart watches should be based on the size of traditional watches. There is no absolute big screen or small screen, but there should be a relatively reasonable size. Now let's follow the embedded editor to understand the relevant content. Q&A: Is it better to have a larger or smaller display screen of a smart watch? For example, men are more suitable for 42mm dials, while women are more suitable for 38mm dials. This classic size has been obtained [Detailed]

Embedded technology has developed very rapidly, with the emergence of highly integrated processors based on SCM and dedicated embedded ARM, and has been widely used in communication, automation, power electronics and other fields. The power industry has also begun to use embedded controllers with rich internal integration resources to form the control system of large-scale switching power supply. Switching power supply is a kind of power supply with high efficiency. It controls the opening and closing of switching devices such as M0S tube and IGBT by the pulse width modulation wave (PWM) with adjustable duty ratio, so as to achieve stable output of voltage and current. Its performance is good or bad [Detailed]

According to foreign media reports, California recently released its 2019~2020 Integrated Resource Plan (IRP). According to the plan, by 2030, solar energy+energy storage projects will dominate the energy structure of the state. The plan points out that by 2030, a battery energy storage system with an installed capacity of 11~19GW will be deployed, with the main purpose of transferring solar power generation to the night. It is reported that compared with the previous Integrated Resource Plan (IRP), the substantial increase in solar power generation and energy storage systems is partly due to the faster price reduction of these two technologies than expected [Detailed]
