The MYD-SAM9G25 Development Board is among MYD-SAM9X5 series based on Atmel AT91SAM9G25 ARM9 processor which is capable of working at up to 400MHz.

The board has a flexible design with one CPU module MYC-SAM9G25 mounted on one base board which is easy for customers to design their own base board or upgrade the CPU module.  The CPU module MYC-SAM9G25 is a tiny controller board which has the SAM9G25 processor, 128MB DDR2 SDRAM, 256MB Nand Flash, 4MB Data Flash, 64KB EEPROM and Ethernet PHY on board and connects with the base board through one DDR2 SO-DIMM 200-pin connector. The base board has carried out a set of rich peripherals by headers and connectors including serial ports, USB Host, OTG, one 10/100Mbps Ethernet, RS485, Micro SD, Audio, etc. The CPU module MYC-SAM9G25 is compatible with Atmel's official SAM9X5-EK and can work on SAM9X5-EK's base board directly.

The MYD-SAM9G25 boards support running Linux 2.6.39 and Andriod 2.3.5 and is delivered with software packages. It is also provided with sample codes bundle for the peripherals using Keil's MDK-ARM to help users evaluate the Atmel AT91SAM9X5 series ARM9 processors. MYIR also offers camera, WiFi, GPS and GPRS modules as add-on options which have greatly enhanced the functions of the development board. MYIR also offers detailed documents, user manual, datasheet in one DVD along with some necessary cable accessories to provide an ideal evaluation kit to help users quickly start their development when getting the goods out-of-the-box.

With rich peripheral set, the boards can be used for a variety of applications such as industrial controls, medical equipment, automation, portable data terminals, biometric security systems, test and measurement instruments, etc.

MYD-SAM9G25 Development Board

Note: The MYD-SAM9G25 has no CAN (CAN0 and CAN1) and only supports one 10/100Mbps Ethernet (J11).

The MYD-SAM9G25 can not support LCD display.
