Giada IB3-281-X7211E Dual-Core Intel Atom x7211E 3.5″ SBC with 12 to 24 V DC Input and Wide Temperature

Data concentrators, building controllers and serial-to-Ethernet gateways spend most of their time waiting on field devices, so a low-power processor and plenty of ports matter more than core count. The IB3-281-X7211E is the dual-core Atom build of the Giada IB3-281 series, a 3.5″ SBC with six serial ports, rated from -20 to 60 °C.

The Intel Atom x7211E has two Alder Lake-N cores at 6 W, half the TDP of the N97 build, which keeps heat down in sealed or crowded enclosures. It comes from Intel’s Atom x7000E embedded line. The board has 8 GB of LPDDR5 at 4800 MHz soldered on, an M.2 M-key 2280 socket for an NVMe SSD on PCIe 3.0 x4, and Intel UHD Graphics driving HDMI, DisplayPort and dual-channel 24-bit LVDS, with two displays active at once. Windows 10, Windows 11 and Ubuntu Linux are supported.

Four RS-232 and two RS-485 ports on headers take meters, drives, legacy controllers and RS-485 sensor buses, and four inputs and four outputs of GPIO handle alarms and relays. A 2.5GbE port on an Intel I226-V and a GbE port on an Intel I210-AT split the field network from the uplink. Two USB 3.2 Gen 1 Type-A ports, one internal USB 3.2 Gen 1 header and four USB 2.0 headers connect peripherals, and an M.2 E-key 2230 socket takes Wi-Fi and Bluetooth. A watchdog timer and an optional TPM 2.0 are listed.

The IB3-281-X7211E runs from 12 to 24 V DC through a lockable DC jack or an internal 4-pin header, with auto power-on so the device restarts after a supply cut. It runs fanless from -20 to 60 °C with 0.7 m/s of airflow. For a full desktop or 4K playback, the IB3-281-N97 offers four cores at 12 W on the same board.
