Product Views and Architecture
Board Layout
Bottom View: The bottom of the ADN553 SBC reveals the front panel connectors, including headers for the Front Panel interface, SPI ROM, Audio, SIM Slot, M.2 E key, 8-bit DIO, LVDS, LCD/Inverter Power, eDP, SATA 3.0, and SATA Power.
Top View: The top side of the ADN553 SBC features key external connectivity ports: three 2.5GbE LAN ports, USB 3.2 Gen2, USB 3.2 Gen1, HDMI, USB Type-C, a System Fan header, DC-in power connector, M.2 M key slot, COM 1 port, M.2 B key slot, USB 2.0 ports, and a DDR5 SO-DIMM memory slot.
Block Diagram
The block diagram illustrates the ADN553's internal architecture, centered around the Intel® Alder Lake-N processor. It connects to DDR5 SO-DIMM memory, LVDS/eDP display outputs, M.2 slots (M key, E key), multiple USB ports (3.2, 2.0), SATA 3.0, 8-bit GPIO, eSPI, SPI ROM, System Fan header, COM1, and audio via Realtek ALC888. The diagram also shows HDMI, USB 3.2, USB 2.0, a Type-C connector supporting USB 3.2/DP Alt. Mode, and three 2.5GbE LAN ports. The system supports a wide range of DC power input (9V~36V).
Mechanical Drawing
The mechanical drawing details the 3.5-inch SBC form factor, with overall dimensions of 146mm (5.75 inches) in length and 102mm (4.02 inches) in width. It specifies the PCB thickness and indicates the placement of mounting holes.
