Brief introduction

The TQ2440 development board is an efficient ARM9E development board with a low price, it characterizes simple method and high performance-price ratio. Based on the Samsung S3C2440 microprocessor, it embodies professional stable power source chip and reset chip to ensure the stability of the system operation. The PCB on the TQ2440 board is designed to be 4-layers board, adopting the ENIG technology and professional equal-length wiring to ensure the completeness of the signals of the key signal wires; manufactured and released under stringent quality control plans.

With the help of the detailed manual, users are supposed to become proficient in the development process of embedded Linux and WinCE operating system, they are supposed to get the basic idea about the WinCE and Linux development in two weeks, so long as they have obtained the basic and necessary knowledge about the C language.

TQ2440 is so powerful that it can work as a laptop type performance. It even support embedded database.TQ2440 is more open source compared to MINI2440.
