DFI EHL051-TCD-6416RE Quad-Core Intel Atom x6416RE Pico-ITX Single Board Computer with Dual GbE and -40 to 85 °C

In a sealed IP-rated enclosure the heat from the processor has nowhere to go but the case walls, so every watt counts. The EHL051-TCD-6416RE is the 9 W quad-core build in the DFI EHL051 series of Pico-ITX single board computers, for designs that need four cores for protocol conversion or data logging without the 12 W of the top builds.

Its Intel Atom x6416RE (Elkhart Lake) has four cores at 1.7 GHz and a 9 W TDP. One DDR4 3200 MHz SO-DIMM takes up to 32 GB with in-band ECC, which protects long-running data buffers on standard modules. Intel UHD Graphics drives HDMI at up to 4096 x 2160 and dual-channel 18/24-bit LVDS at 1920 x 1200, so a local status panel and an external screen can run together.

For I/O the board has two GbE ports on Intel I226 controllers, two rear USB 3.2 Gen 2 ports and two internal USB 2.0 headers. Two RS-232/422/485 ports and 8-bit DIO sit on internal headers for sensors, meters and relays. The M.2 E-key (2230) takes Wi-Fi and Bluetooth, the M.2 B-key (2242/3042) takes a cellular module with its SIM slot or an SSD, and one SATA 3.0 port adds a drive. TPM 2.0 is on board.

The EHL051-TCD-6416RE takes 12 V DC on a 2-pin terminal block and runs from -40 to 85 °C on a fanless heatsink, with CE, FCC, UKCA, RoHS and KC compliance and a 1 to 255 second watchdog. The EHL051-TCD-6425RE lifts the budget to 12 W at 1.9 GHz, while EHL051-TCD-6413E keeps 9 W with bursts to 3.0 GHz across the same temperature range.
