TechInsights Teardown: Apple HomePod 2nd Gen

Smart home devices, voice assistants in particular, have been extremely popular devices among consumers since the inception of Amazon Alexa.

Soon other hubs were launched to compete with the Alexa devices like Google’s home hub and the HomePod from Apple. The electronic device giant released the second version of its HomePod earlier this year.

However, unlike the first-generation smart home device, the second-generation hub contains a faster processor, thread radio, temperature and humidity sensing and is Matter standard compatible meaning that any smart home device that is also Matter compatible can be connected to the HomePod. While that is only a few devices today, it will soon be many more.

The HomePod also comes with Siri as the smart home voice assistant allowing users to set multiple timers, check the weather, put things on a calendar and get news.

The HomePod includes the Apple dual core applications processor and 1 GB of mobile DRAM for higher levels of processing power compared to the original generation.

The following is a partial deep dive into the Apple HomePod 2^nd Gen conducted by TechInsights.
