Pak-tab-design and development of an embedded hardware platform for android applications

Abstract

This project carried out the design and development of an embedded hardware circuit board for android applications using Samsung S5PV210 Processor. The designed hardware possesses GPS, Wi-Fi, capacitive screen, G-sensor and will have ports/interfaces like USB, HDMI, SD-card and Ethernet. The embedded board may also be used with WinCE and Linux. Altogether the embedded hardware board constitutes a tablet that offers various useful functions. The steps that were involved in making a tablet included the designing of schematics and PCB layout, debugging of that PCB layout and then its fabrication. Furthermore, Device-Drivers and Android applications were installed onto the tablet. The schematics were made using Altium Software using the knowledge of linking the sub-sheets to the main sheet. The PCB layout was designed and manually routed according to the Schematics provided, so that minimum errors are present in the PCB. Further Debugging of the PCB layout was done to ensure that there were no mistakes. When the circuit was verified, it was sent for Fabrication. Methods of installation of Device drivers and booting techniques were conducted on the kit. Furthermore, a study of android basic applications for verification of tablets was conducted.
