One of the latest incarnations of the Echo Dot boasts premium sound and an ability to pair up with Fire TV devices for a home theater audio experience. Construction-wise, there are usually a few changes from one generation of Echo devices to the next, and sometimes between early and later models of the same generation. With that in mind, we disassembled a 4th generation … [Read More...] about Teardown: Amazon 4th generation Echo Dot
