DFI QCS051-BCC-4830 Qualcomm QCS5430 (Dragonwing) Pico-ITX Board with 4GB LPDDR5x Memory and 128GB UFS

Not every Arm design needs the full AI throughput of the QCS6490. Thin clients, operator panels and gateways that run a small classification model, or none at all, can use the QCS051-BCC-4830, the QCS5430 build of the DFI QCS051 series, on the same 2.5″ Pico-ITX board as its eight-core siblings.

The Qualcomm Dragonwing QCS5430 (FP1) has six Kryo 670 cores at up to 2.1 GHz and an AI engine rated at 3.5 TOPS (INT8), which suits light workloads such as simple classification or anomaly checks next to the main application. Memory is 4 GB of soldered LPDDR5x, storage is 128 GB of UFS 3.1 with a microSD 3.0 slot, and the Adreno 643L GPU drives one HDMI 1.4 output for a local screen. Linux Yocto 4.0 is the default image, with Ubuntu 20.04 on request.

The I/O matches the rest of the series, so an enclosure designed for one build fits all three. A GbE port on an ASIX AX88179A controller and two USB 3.1 Gen 1 Type-A ports face outward, while three USB 2.0 headers, one RS-232 port, one CAN FD port and 8-bit DIO sit on the board. Two four-lane MIPI CSI-2 connectors accept cameras, and M.2 B-key 3052 (with a nano SIM slot) and E-key 2230 sockets take 4G or 5G and Wi-Fi with Bluetooth. A Type-C download port and a Micro USB debug port serve as service ports for flashing and debugging.

The QCS051-BCC-4830 runs fanless with a heat spreader from 5 V DC on a 2-pin connector, operates from 0 to 60 °C and carries CE, FCC, UKCA and RoHS compliance. If the model grows, the QCS051-BCC-4890 moves to the eight-core QCS6490 with 12 TOPS on the same footprint, and the QCS051-ECC-8890 adds 8 GB of memory and a -25 to 75 °C range.
