The Raspberry Pi Compute Module 3+ Lite contains the guts of a Raspberry Pi 3 Model B+ (the BCM2837 processor and 1GB LPDDR2 RAM). This module allows a designer to leverage the Raspberry Pi hardware and software stack in their own custom systems and form factors. In addition this module has extra IO interfaces over and above what is available on the Raspberry Pi model A/B boards, opening up more options for the designer.
This is all integrated onto a small (67.6mm × 31mm) board that fits into a standard DDR2 SODIMM connector. 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 all the tricky bits have been put onto the Module itself.
The CM3+ Lite product is the same as CM3+ except the eMMC Flash is not fitted, and the SD/eMMC interface pins are available for the user to connect their own SD/eMMC device. Note that the CM3+ is electrically identical and, with the exception of higher CPU z-height, physically identical to the legacy CM3 products.
Note: The CM3+ modules require a software/firmware image dated November 2018 or newer to function correctly.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
