Raspberry Pi in Embedded Systems Design

The Raspberry Pi is difficult to use in an embedded application because the unneeded connectors get in the way. The Compute Module was made to solve that problem. The Arm processor is a 200 pin DDR2 SO-DIMM module, aka, a “Sodium” CPU. It has a Broadcom BCM2835 ARM1176 CPU with 512 MB of RAM, a 4 GB eMMC device, USB, high speed video ports, GPIO, PWM, UART, PCM/PDM Audio In and Out, multiple 32-bit timers, and two SPI ports, which makes it an ideal controller for many embedded applications.
