Hands-On Embedded Programming with C++17

System-on-Chip/Single Board Computer

Systems-on-Chips (SoCs) are similar to MCUs, but distinguish themselves from those types of embedded systems by having some level of integration while still requiring a number of external components to function. They are commonly found as part of a single board implementation (Single Board Computer (SBC)), including the PC/104 standard, and more recently form factors such as the Raspberry Pi and derivative boards:
