Description

The Embest Mini2410-III processor card measuring only 50mm by 60mm is an ideal embedded microprocessor solution. The tiny board is based on the Samsung S3C2410A ARM920T processor. The processor card takes full features of S3C2410A and the connection between the processor card and your carrier board is through two 4mm height, 0.6mm space and 140-pin Board-to-Board female connectors. A complete set of peripherals including LCD, AD, SPI, Uart, USB, SD/MMC Card, Ethernet (DM9000AE), IIS, I2C, RTC, PWM, GPIO, Local bus and all I/O CPU lines can be extended via two 4mm height 0.6mm space 140-pin board-to-board connectors. The fully expansion can be used adapted to customer requirements.

Integration of the Embest Mini2410-III processor card to customer special design is fully supported by Embest technologies. The processor card has no software on itself originally. Customers can develop the software according to their own designs. Embest also designed one PC/104 carrier board for this tiny CPU board, the whole kits is called EM104V1 and is provided with Linux2.6.14 BSP, customers can use it already if cater to your needs. Embest also offers professional custom software and hardware development and you can leverage our experience to increase your own productivity. This processor card provides users with a flexible development environment based on S3C2410A and a shortened development timeframe, which would be a best choice for developers.
