Olimex - SAM7-LA2 DEVELOPMENT BOARD FOR AT91SAM7EA2 ARM7TDMI-S MC |
|
|
|
|
|
| |
| The SAM7-LA2 is a good platform for low power uclinux applications - AT91SAM7A2 targets low power applications. The on board 4MB of RAM and 1 MB of Flash allows RTOS such as uclinux, ucos, etc to be used. The CAN , RS232 and 100Mbit Ethernet ports allow this board to be used in many applications. |
