Chapter 1: Overview
1 System Overview
1.1 Introduction
K7 is an MID (Mobile Internet Devices) developed by OpenSourceMID.org community
members. It is based on TI OMAP 3530, a high performance processor. This product is
flexible, it has a nice shape and powerful functions. It supports camera video input,
3G/Wi-Fi wireless network, Bluetooth data transmission, GPS Navigation and G-sensor. It
has a touch screen with high definition and high hardness. Windows Embedded CE 6.0
will be pre-installed when it leaves the factory.
