Raspberry Pi Compute Module 3
The Raspberry Pi Compute Module 3 (CM3) is a DDR2-SODIMM-mechanically-compatible System on Module (SoMs) containing the same processor, memory, and supporting power circuitry as the Raspberry Pi 3.
These modules allow designers to leverage the Raspberry Pi hardware and software stack in their own custom systems and form factors. In addition the modules have extra IO interfaces over and above what is available on the Raspberry Pi boards, providing more options for the designer. The Raspberry Compute Modules 3 are suitable for designers who are happy with Raspberry Pi 3 functionality but require a smaller form factor (67.6 mm x 31 mm) for their embedded designs.
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. You get the full flexibility of the BCM2837 SoC (which means that many more GPIOs and interfaces are available as compared to the Raspberry Pi), and designing the Module into a custom system should be relatively straightforward as all the tricky bits are pre-built into the module.
The Compute Module 3 Lite contains the following components contained within a 200 pin SODIMM design:
- Broadcom BCM2837 Processor (1.2GHz)
- 1GB LPDDR2 RAM
- 35u Hard Gold Plated IO Pins
- DDR2-SODIMM, Mechanically-Compatible System on Modules (SoMs)
- 4 GB eMMC Flash memory. Also these modules have extra input/output (I/O) interfaces in addition to the Raspberry Pi model A/B boards.
- 67.6mm x 31mm Board
