The Omega2S is a surface-mount packaged version of the Omega2 module, which has been developed by the team at Onion Corp. It is based on the same functional design, and includes the same MT7688 SoC Microprocessor, DDR2 DRAM and Flash memory used in the original through-hole version of the Omega2.

• Low profile – only 2.8 mm high!
• Designed for high-volume manufacturing of surface mount PCBs with pick and place machinery
• Two memory size versions, similar to the Omega2
  • Omega2S 64 MB DRAM, 16 MB Flash
  • Omega2S+ 128 MB DRAM, 32 MB Flash
• UFL Connector for External Wifi Antenna attachment
• FCC and CE Certified

The Compute Module 3+ (CM3+) is a Raspberry Pi 3 Model B+ in a flexible form factor, intended for industrial applications. The CM3+/Lite contains the guts of a Raspberry Pi 3 Model B+ (the BCM2837 processor and 1GB RAM).

• Broadcom BCM2837B0, Cortex-A53 (ARMv8) 64-bit SoC @ 1.2GHz
• 1GB LPDDR2 SDRAM

This is all integrated onto a small (67.6mm × 31mm) board that fits into a standard DDR2 SODIMM connector. The 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 than with a standard Raspberry Pi), and designing the Module into a custom system should be relatively straightforward because we’ve put all the tricky bits onto the Module itself.
