Raspberry Pi Compute Module

by www.embedds.com:

Raspberry Pi has been very popular small computer board. It’s initial layout is quite flexible that allows it to use as standalone computer or embedded device with controllable I/Os. Probably standard Raspberry Pi is more oriented to be small single board computer, where you can connect peripherals like keyboard, mouse, display, Ethernet. The I/O part seemed to be left on a side. Eventually extension boards started to appear to fill the need of functionality like ADC, DAC, more digital I/Os. Eventually you end up stacking stuff on top like Arduino. But we like elegant things don’t we? So Raspberry Pi team has been working on different Raspberry Pi concept – Compute module. This is smaller module which have same BCM2835 processor, same RAM. Instead of SD flash there is a 4Gbyte flash memory. Practically this is it. Module is traced on DDR2 SODIMM sized PCB which actually fits this connector.

Strategic Test has announced a new low-cost addition to its line of Freescale-based i.MX multimedia processor modules. The TX-28S has a 200-pin SODIMM form factor measuring just 68 x 25 mm and contains a 454 MHz i.MX283 processor (based on the ARM926EJ-S core) along with 64 MB DDR SDRAM and 128 MB NAND flash memory. The module is targeted at embedded fanless applications where low price, small size and low power consumption are critical factors. A long-term availability of seven years is guaranteed.

The DIMM module features include 10/100 Mbps Ethernet, two high-speed USB 2.0 ports, a colour LCD controller, a 4/5-wire touchscreen interface, and UART, SD-Card, I²C, PWM, serial audio and SPI interfaces. It is pin compatible with the manufacturer’s existing modules based on other Freescale i.MX processors, which allows developers to create scaleable systems. All modules can be supplied with the Development Kit-5 hardware reference platform, which supports both Linux and Microsoft Windows Embedded CE 6.0. [via]
