4-inch Embedded Single Board Computer (SBC) building on the compact foundation of embedded SBCs, the 4-inch standard form factor offers a slightly larger footprint to accommodate an even greater array of onboard interfaces and connectivity options. It delivers robust computing performance, wide-temperature support, and reliable fanless operation. This board is engineered for embedded projects that require more extensive native I/O—such as additional display ports, network interfaces, or expansion slots—without moving to a larger motherboard format. Key Advantages: Optimal balance of size and I/O density, robust performance, reliable operation, design flexibility.
