Mini2440 Development Board
mini2440 - 3.5 inch TFT Touch Screen S3C2440 ARM9 Development Board (1GB NAND FLASH)
Mini2440 is a practical low-cost ARM9 development board, is currently the highest in a cost-effective learning board. It is for the Samsung S3C2440 processor and the use of professional power stable core CPU chip to chip and reset security permit system stability. The mini2440 Immersion Gold PCB using the 4-layer board design process, professional, such as long-wiring to ensure that the key signal lines of signal integrity, the production of SMT machine, mass production; the factory have been a strict quality control, with very detailed in this manual can help you quickly master the development of embedded Linux and WinCE process, as long as there is C language based on the general entry to two weeks. Users can go to our website, http://www .arm9.net, and download the latest update to inform the latest manuals and systems.
