Raspberry Pi Compute Module 3+ Lite

CM3+/Lite compute module is a Raspberry Pi 3 Model B+ (the BCM2837 processor and 1GB RAM) without on-board eMMC Flash. 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 the Pi Foundation has put all the tricky bits onto the Module itself.
