Compute Module 3, Raspberry Pi 3 in a flexible form factor, with 4GB eMMC Flash
The Compute Module 3 contains the guts of a Raspberry Pi 3 (the BCM2837 processor and 1GB RAM) as well as a 4GB eMMC Flash device (which is the equivalent of the SD card in the Pi).
The Pi 3 has a processor speed of 1.2GHz and runs at roughly 10 times the speed of the Pi 1 due to its quad-core CPU.
This is all integrated on to a small 67.6mm x 31mm board which fits into a standard DDR2 SODIMM connector (the same type of connector as used for laptop memory).
The Flash memory is connected directly to the processor on the board, but the remaining processor interfaces are available to the user via the connector pins.
Product Description:
64-bit 1.2GHz quad-core ARM Cortex-A53 processor
1GB RAM
4GB eMMC Flash (for CM3 only, not for CM3L)
200PIN SODIMM connector (35U hard gold plating I/O pins)
48 x GPIO
2 x I2C
2 x SPI
2 x UART
2 x SD/SDIO (1x SD pin on CM3 has been used for 4GB eMMC Flash)
1 x HDMI 1.3a
1 x USB2 HOST/OTG
1 x DPI (parallel RGB display)
1 x NAND(SMI)
1 x 4-lane CSI Camera Interface (up to 1Gbps per lane)
1 x 2-lane CSI Camera Interface (up to 1Gbps per lane)
1 x 4-lane DSI Display Interface (up to 1Gbps per lane)
1 x 2-lane DSI Display Interface (up to 1Gbps per lane)
Compared to CM1, the CM3/CM3L supports more OS, like Windows 10 (the free IOT-specific version from Microsoft)
