Tiny2451 Development Kits Feature

Tiny2451 is a high-performance ARM926EJ core board, from FriendlyArm design, production and distribution sales. It uses Samsung S3C2451 as the main processor, running at up to 400MHz. Tiny2451 Contain one CPU board(Tiny2451) and one base board(Tiny2451SDK).

The CPU board(Tiny2451) use a 2.0mm pitch double-pin that lead out 180Pin, which size is 64x50mm. It comes standard with 256MB DDR memory and 256MB Nand FLash.

The Tiny2451SDK is the Base Board for the Tiny2451 CPU board, it comes with a variety of common standard interfaces, such as USB Host, SD card, DB9 serial port, RJ-45 Ethernet port, audio input and output ports, as well as some of the on-board resources testing devices such as EEPROM, buzzer, keypad, GPIO ports, SDIO ports, etc.

For the Tiny2451, we do the superboot-2451 for it, then you can update the system by SD card auto.
