DFI QCS051-ECC-8890 Octa-Core Qualcomm QCS6490 Arm Single Board Computer with 8GB LPDDR5x Memory and -25 to 75 °C

Robots that cross a loading yard, cameras on a mast and devices in unheated vehicles see temperatures an indoor board is not rated for. The QCS051-ECC-8890 is the extended-temperature build in the DFI QCS051 series, an Arm single board computer on the 2.5″ Pico-ITX size, operating from -25 to 75 °C.

Its Qualcomm Dragonwing QCS6490 has eight Kryo 670 cores at up to 2.7 GHz and an AI engine rated at 12 TOPS (INT8). With 8 GB of soldered LPDDR5x, twice the other builds, there is room for larger detection models, several camera buffers or a navigation stack running next to the inference. Storage is 128 GB of UFS 3.1 plus a microSD 3.0 slot, and the Adreno 643L GPU drives one HDMI 1.4 output. Linux Yocto 4.0 is the default image, with Ubuntu 20.04 on request.

Two four-lane MIPI CSI-2 connectors take cameras without a USB bridge. CAN FD connects motor controllers and battery management, while an RS-232 header and 8-bit DIO handle older devices and discrete signals. Networking is one GbE port on an ASIX AX88179A controller, with an M.2 B-key 3052 socket and nano SIM slot for 4G or 5G and an M.2 E-key 2230 socket for Wi-Fi and Bluetooth. Two USB 3.1 Gen 1 Type-A ports sit on the edge with three USB 2.0 headers, and a Type-C download port and a Micro USB debug port serve as service ports for flashing and debugging.

The QCS051-ECC-8890 runs fanless from 5 V DC on a 2-pin connector, with a heat spreader as standard and a DFI heatsink listed for the -25 to 75 °C grade, and carries CE, FCC, UKCA and RoHS compliance. For indoor equipment, the QCS051-BCC-4890 offers the same QCS6490 with 4 GB at 0 to 60 °C, and the QCS051-BCC-4830 drops to the six-core QCS5430 with 3.5 TOPS.
