SAMSUNG Exynos4412 development kits Tiny4412

Author:  From:  Date:2013/12/4

Tiny4412 is a high-performance quad-core Cortex-A9 core board, from CoreWind design, production and distribution sales. It uses Samsung Exynos4412 as the main processor, running at up to 1.5GHz. Tiny4412 Contain one CPU board(CM-Tiny4412) and one base board(Tiny4412SDK).
 
The CPU board(CM-Tiny4412) use a 2.0mm pitch double-pin (P1, P2, P3, P4) that lead out 208Pin, which size is 74x55mm. It comes standard with 1GB DDR2 memory and 4GB of high performance eMMC flash (optional 8/16/32GB eMMC Flash).
 
The Tiny4412SDK is the Base Board for the Tiny4412 CPU board, it comes with a variety of common standard interfaces, such as HDMI output, 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.
