The Raspberry Pi Compute Module 3 Lite (CM3L) is identical to the Compute Module 3, however, the CM3L doesn’t have the 4GB of onboard eMMC flash storage, but instead breaks the SD/eMMC bus pins out to the edge connector pins which allows you to implement that storage external to the board.
The Compute Module 3 Lite brings the same processing power that the Raspberry Pi 3 does but in a DDR2 SODIMM card form factor which makes it better suited to commercial and industrial applications. The SoC BCM2837 delivers a 1.2GHz quad-core processor, 1GB of RAM, plus all of the peripheral functionality and GPIO pins are available through the SODIMM connector.
The 200-pin DDR2 SODIMM form factor allows for cheaply and readily available sockets to be used for new designs, although it’s important to note that the CM3L pinout is different to the previous Computer Modules are they are not electrically compatible.
