A modular smartphone will allow users to choose their own hardware based on their needs and interests. Google would manufacture and sell the phone frame as well as modules created by individual manufacturers that can be added to it like Legos. Modules would range from a screen to a camera to speakers to even a pedometer.
The base model features a 1280×720 display, light and proximity sensors, dual application processors including a Marvell PXA1928 processor and an NVIDIA Tegra K1 processor, 5-megapixel rear camera, Wi-Fi, Bluetooth, 3G modem with Band 2 antenna, Band 5 antenna, microUSB port, battery, and speaker. Google revealed that the Spiral 2 prototype includes 11 working modules as of now;
Modules include 3G, Wi-Fi, Bluetooth, Receiver with light and proximity sensors, USB charger module, and a 2×2 battery module. The prototype also features the electro-permanent magnets in the exoskeleton, saving space in the modules.
Google says that the price might be in the range from $50 to $100.
The latest version of the Module Developers Kit (MDK), MDK 2.0, was also released, and is available for download via the Project Ara site.
Google plans to unveil a modular smartphone in Puerto Rico this year as part of a pilot program.
