When selecting an SBC, you must prioritize the Processor (SoC) architecture, typically ARM or x86, depending on your software compatibility needs. Evaluate the RAM capacity and type (e.g., LPDDR4 vs. LPDDR5) to ensure it handles your multitasking requirements. Additionally, check the I/O peripheral support, including the number of USB 3.0 ports, HDMI versions (supporting 4K/8K), and GPIO pin headers for hardware expansion. For industrial applications, ensure the board supports eMMC flash storage or NVMe M.2 SSDs for higher reliability compared to standard microSD cards.
