LMYN Computer Components Editorial Review

**** The 2-Channel Micro USB Relay Module USB Smart Control Switch has garnered a mix of appreciation and challenges from its users. Many customers have noted the initial ease of setup, stating that they were able to get the module up and running fairly quickly. The distinctive indicator lights on the device are also mentioned as a positive feature, although some users found them to be overly bright. However, users have encountered significant issues with device recognition across multiple operating systems. Testing with Mac, Linux, and Raspberry Pi revealed that the module was not being recognized as a USB device, raising concerns about compatibility. While some were able to successfully interface with the module through command line commands under certain conditions, the fact that the device could not be recognized Consistently on other machines led to frustration. Another point of contention is the types of relays used; users expressed a desire for latching relays which would maintain their state when the power is cut. This feature is particularly important for users looking for more advanced functionality. Additionally, several users reported durability issues, notably regarding the USB connector which has been prone to breaking upon minimal force. In summary, while the 2-Channel Micro USB Relay Module offers ease of use and some beneficial features, its compatibility issues and physical durability concerns can be significant drawbacks for potential users. **
