3 These modules allow a designer to leverage the Raspberry Pi hardware andsoftware stack in their own custom systems and form factors. In addition these modules have extra IOinterfaces over and above what is available on the Raspberry Pi model A/B boards, opening up moreoptions for the CM3+ contains a BCM2837B0 processor (as used on the Raspberry Pi 3B+), 1 Gbyte LPDDR2 RAM and eMMC Flash. The CM3+ is currently available in 4 variants, CM3+/8GB, CM3+/16GB,CM3+/32GB and CM3+ Lite, which have 8, 16 and 32 Gigabytes of eMMC Flash, or no eMMC Flash, CM3+ Lite product is the same as CM3+ except the eMMC Flash is not fitted, and the SD/eMMCinterface pins are available for the user to connect their own SD/eMMC that the CM3+ is electrically identical and, with the exception of higher CPU z-height, physicallyidentical to the legacy CM3 + modules require a software/firmware image dated November 2018 or newer to function 2 Compute Module 3+ DatasheetCopyright Raspberry Pi (Trading) Ltd.

6 20194 Mechanical SpecificationThe CM3+ modules conform to JEDEC MO-224 mechanical specification for 200 pin DDR2 ( )SODIMM modules and therefore should work with the many DDR2 SODIMM sockets available on themarket.(Please note that the pinout of the Compute Module is not the same as a DDR2 SODIMM Module ; they are not electrically compatible.)The SODIMM form factor was chosen as a way to provide the 200 pin connections using a standard,readily available and low cost connector compatible with low cost PCB maximum component height on the underside of the Compute Module is maximum component height on the top side of the Compute Module is Compute Module PCB thickness is +/- that the location and arrangement of components on the Compute Module may change slightlyover time due to revisions for cost and manufacturing considerations; however, maximum componentheights and PCB thickness will be kept as 2 gives the CM3+ mechanical 2: CM3+ Mechanical Dimensions8 Release 2 Compute Module 3+ DatasheetCopyright Raspberry Pi (Trading) Ltd.
