Features will be finalized in the official release.  Why This Upgrade? Over time, we’ve received valuable feedback from many of our users: “The controller works great,...

When choosing an underwater thruster, many users find themselves torn between the AQ1020 and its upgraded version, the AQ1121. On the one hand, the AQ1020 delivers a thrust of up to 24 kg at 48V, which is even higher than the AQ1121’s 21 kg;on the other hand, the AQ1121 is marketed as the ‘upgraded version’. 👉 So the question arises:What exactly has been upgraded in the AQ1121? Is it worth choosing? This article will help you fully understand the differences between the two by examining thrust, the control system (FOC), real-world user experience and application scenarios. Product Overview AQ1020 Underwater...

Chapter 1: Introduction to the Modbus Protocol The Modbus protocol is a universal language used in electronic controllers. Through this protocol, controllers can communicate with one another, and controllers can communicate with other devices via a network (such as Ethernet). It has become a universal industrial standard. With it, control devices produced by different manufacturers can be connected into an industrial network for centralised monitoring. This protocol defines a message structure that a controller can recognise and use, regardless of the type of network through which communication takes place. It describes the process by which a controller requests access to...

How to Choose the Right Underwater Thruster for Your Project With the development of water recreation, electric boats, and underwater robotics technologies, underwater thrusters are becoming a core power component in an increasing number of projects. Whether it's kayaks, small boats, or ROV underwater robots, electric underwater thrusters offer significant advantages such as quiet operation, high efficiency, ease of control, and simple maintenance. I. What is an underwater propulsion device? An underwater propulsion system is an electric propulsion device that generates forward or backward propulsion by pushing against water. A complete underwater propulsion system typically includes: a brushless motora propellera...
