DFI ADN553-BN-N305 Intel Core i3-N305 (Alder Lake-N) 3.5″ Embedded Board with 9 to 36 V DC Input and Triple 2.5GbE

Edge gateways and vision boxes tend to gather jobs over time: a protocol bridge becomes a data historian, then a video recorder, then a local dashboard. Eight cores give that growth somewhere to go. The ADN553-BN-N305 is the top compute option in the ADN553 series, a 3.5″ embedded board with triple 2.5GbE for the networks those jobs connect.

The Intel Core i3-N305 is an eight-core Alder Lake-N processor running up to 3.8 GHz within a 15 W TDP. The extra cores suit containerized gateway software, several camera streams or an HMI alongside control logic. One DDR5 4800 MHz SO-DIMM slot takes up to 16 GB, and Intel UHD Graphics handles HEVC, VP9, AV1 and AVC decode and HEVC, VP9 and AVC encode in hardware. A discrete TPM 2.0 and a programmable 1 to 255 s watchdog support secure, unattended operation.

Three 2.5GbE ports on Intel I226V controllers carry camera, plant and uplink traffic on separate interfaces. Displays run from HDMI, USB-C with DisplayPort Alt Mode and an internal eDP connector up to 4096 x 2160 at 60 Hz. Two USB 3.2 Gen 2 and one USB 3.2 Gen 1 Type-A port sit on the rear, with two USB 2.0 headers, one RS-232/422/485 port and 8-bit DIO inside. M.2 sockets take a PCIe or SATA SSD, a 4G or 5G modem with SIM and a Wi-Fi card.

The ADN553-BN-N305 runs fanless from -5 to 65 °C on 9 to 36 V DC, with CE, FCC, UKCA, KC and RoHS compliance. If your panel is LVDS and four cores are enough, the ADN553-BN-N200 runs at 6 W. The ADN553-BN-N97 keeps eDP with four cores at 12 W for a lower power budget than this board.
