1. Purpose
The main device in the catalog — a compact fanless computer for on-site inference (machine vision, control cabinet, production line): metal heatsink enclosure, eight-core RK3588S with NPU, two USB 3.0 ports for cameras, Gigabit Ethernet, NVMe for storage. Takes 1–2 USB cameras or IP cameras over the network and runs your model on the NPU in a container. No radio: network over cable. Industrial version (−40…+70 °C, CAN, RS-485) — see the options below. Need a board for your own enclosure — PH-K01; need CUDA — PH-J31.
2. Platform
| SoC / accelerator | Rockchip RK3588S — 4×Cortex-A76 2.4 GHz + 4×Cortex-A55, 3-core NPU |
|---|---|
| TOPS INT8 dense | 6 TOPS INT8 densemethod: Rockchip datasheet, RKNN 2.3.x; NVIDIA publishes sparse figures — the numbers are not directly comparable, we compare FPS on the same models |
| Memory | 8 GB LPDDR4x (base); 16 GB — option |
| Storage | 64 GB eMMC + M.2 2242 NVMe (256 GB option; with an M.2 accelerator installed, the system stays on eMMC) |
3. Interfaces
| USB | 2×USB 3.0 Type-A (UVC cameras), 1×USB-C (service, flashing) |
|---|---|
| Ethernet / PoE | 1×GbE RJ-45 |
| RS-485 / CAN / RS-232 | RS-232 (attached PC / service); RS-485 and CAN — in the industrial version |
| GPIO / relay | 2×GPIO, 1×relay (option), reset button, status LED |
| M.2 | M.2 M-key 2242, PCIe 2.1 ×1 — NVMe or M.2 NPU accelerator (single slot; card form factor to match the box slot); M.2 2230 E-key for Wi-Fi — depends on the enclosure variant |
| Video output | HDMI 2.0 — service |
| Wi-Fi / BT / LTE | noneno radio modules by design: no FSB notification needed, fewer security questions on site; network over cable. A Wi-Fi module is an option, imported with notification. |
4. Power and thermal
| Power input | 12 V DC (9–24 V), 5.5×2.1 mm jack; 12 V 2 A adapter included; 802.3at PoE splitter — option |
|---|---|
| Power consumption (typical) | ≈6 W at 2×1080p streams |
| Power consumption (peak) | ≤12 W |
| Cooling | passive, heatsink enclosure |
| Enclosure temperature in a closed cabinet at +40 °C ambient | measured after the first sample is tested; we publish the measurement, not a datasheet value |
5. Mechanical
| Dimensions | ≈190×90×50 mm with mounting ears |
|---|---|
| Weight | ≈600 g |
| Mounting | desk / wall (mounting ears included); VESA 75/100; DIN rail and terminal-pedestal bracket — options |
| Connectors | screw-lock / latching connectors, cable tie included |
6. Environment and protection
| Operating temperature | 0…+50 °C (in a closed cabinet); storage −20…+60 °C; industrial version −40…+70 °C |
|---|---|
| Ingress protection | IP40 |
| Vibration / shock | EN 60068-2-6 (vibration), EN 60068-2-27 (shock) — test report with the first samples |
7. Bench measurements
Measurements are expected with the first samples. What we measure: FPS INT8 YOLOv8n; FPS INT8 YOLOv8s; FPS INT8 YOLO11n; FPS INT8 YOLO11s; FPS INT8 ResNet50; FPS INT8 OCR (PP-OCRv4 rec); 1080p streams; accuracy after quantization.
