The MYD-SAM9X25 development board contains a CPU module with an Atmel AT91SAM9X25 ARM9 processor running at 400 MHz. This is a full-function evaluation kit with rich peripheral interfaces and includes Linux 2.6.3 and Android operating systems with source code.

The board features 256MB DDR2 SDRAM, 256MB NandFlash, 4MB DataFlash and 64KB EEPROM memory. The on-board interfaces include USB Host/OTG, Ethernet (two ports), CAN, RS485, SPI, etc. The MYD-SAM9X25 board can run Linux and Android, and is delivered with full peripheral driver source code so that you can evaluate the SAM9X25 processor and quickly develop your own applications.

The MYD-SAM9X25 development board is provided with detailed schematic documents, datasheet, user manual and fully developed Linux and Android BSP. These allow you to evaluate, customize, and develop hardware and software to cover many fields such as consumer electronics, printers, video processors, industrial control, display systems, security devices, electric power control systems, and web terminals.

The MYC-SAM9X25 CPU module plugs in via an SO-DIMM200 connector, and can be replaced by other modules so you can evaluate the different processors in the Atmel SAM9Gxx and SAM9Xxx series. The differences between the five available processors is as follows:

	LCD Controller	Camera Interface	EMAC	Dual CAN	UART/SPI/TWI	Kit with Base Board
AT91SAM9G15	√				6/5/3	MYD-SAM9G15
AT91SAM9G25		√	√		7/6/3	MYD-SAM9G25
AT91SAM9G35	√		√		6/5/3	MYD-SAM9G35
AT91SAM9X25			2x	√	7/6/3	This kit
AT91SAM9X35	√		√	√	6/5/3	MYD-SAM9X35

See the Atmel SAM9X25 Page for a datasheet and other documentation on the CPU.

The options below allow you to order extra or alternative CPU modules. If you want to be able to use an LCD touchscreen with one of the alternative CPU modules, you should start with one of their kits (e.g. MYD-SAM9G15, MYD-SAM9G35, MYD-SAM9X35), as they have an LCD option selector. From those pages you still can add the SAM9X25 CPU module as an alternative at a reduced price. An LCD option isn't shown on this page because the SAM9X25 CPU does not have an LCD controller. Note that the other CPU modules have an operating temperature range of 0 to 70 °C. Industrial-range versions may be available on request.
