TechInsights Teardown: Amazon Echo Show 15

15 July 2022

Home assistants have come a long way since the inception of the original Amazon Echo as the first smart speaker for consumers in the home.

The first generation of Alexa-enabled assistants only had basic functions, such as broadcasting the news and weather and playing music. However, as technology evolved and more smart home devices came online, Amazon’s voice assistants were able to connect to these devices for control.

Other skills were developed to help smart home consumers do anything from connect to local radio or tell stories to children and everything in between.

Enter the Amazon Echo Show 15 with a 15.6 inch full HD smart display and 5 megapixel camera. It can power widgets to keep the family on track with shared calendars, personal sticky notes, to-do lists, shopping lists and much more.

Additionally, the Amazon Echo Show 15 can be used for entertainment options such as Prime Video, Netflix, Hulu and other streaming accounts, podcasts or audiobooks. This is in addition to performing the same functions as other Amazon voice assistants.

The smart home device is powered by Amlogic’s octa-core ARM Cortex multimedia processor and contains 1 GB of LPDDR4x SDRAM multichip memory from Samsung and additional 2 GB of mobile LPDDR4 SDRAM from Micron.

The following is a partial deep dive into the Amazon Echo Show 15 from TechInsights.
