There is an arm9 core board that I would like to introduce to all of you, please check it out as follows:

The Embest MBC-SAM9G20 Core Board, measuring 45mm x 52mm, is a very small size, low power consumption but high performance arm9 based processor board. It is based on an ATMEL AT91SAM9G20 ARM926EJ-S core based microprocessor, with 64KB ROM and 16KB SRAM on-chip memories. The board features a Micro USB port, a Debug UART port, a 5V power port and comprehensive external memories: 4MB DataFlash,256MB NandFlash,64KB EEPROM and 64MB SDRAM. It is so tiny that it can reduce much space of your products. You can use it easily to complete your project development and save much of your time to the market.
