AT91SAM9G25 Linux SoM, 128/256MB DDR2, 256MB NAND, Ethernet PHY US$49.00

AT91SAM9G25 Linux SoM, 128/256MB DDR2, 256MB NAND, Ethernet PHY

CORE9G25 is a cost-effective System-on-Module (SoM) that can reduce the development time needed to design a low-power and low-EMI Linux Embedded device using an Atmel AT91SAM9G25 CPU.

The more complex hardware like CPU, RAM, Flash, Ethernet PHY, power and EMI components are integrated on a single SMD component at just 40×40 mm (1.57 × 1.57 inches) using a complex six-layer PCB. You can design your hardware around it.

To aid in initial development, you can purchase the CORE9G25-CON Development Board which has this module on it.

The CORE9G25 is based on the Acme Systems Aria G25 module, using the same size and pinout, but adding NAND Flash. It comes with a Buildroot Linux system pre-loaded in the NAND Flash, but also can boot more complex Linux such as Debian from an SD card.
