PH-M24 — M.2 accelerator 24 TOPS
PH-M24 — ПХ-М24 in Russian documents
M.2 M-key 2280 card with the Axera AX8850 NPU: 24 TOPS INT8, 8 GB on the card, ≤7 W, hardware decode of 16×1080p — for the PH-K40 / PH-K01 slot or an x86 PC you already have.
Outline drawing; product photos are on the product page. Dimensions: 22×80×9 mm (M.2 2280, with heatsink).
- Axera AX8850: 24 TOPS INT8 dense, 8 GB LPDDR4x on the card, 16×1080p / 8K decode
- M.2 M-key 2280, PCIe; ≤7 W, passive heatsink — fits the thermal budget of the box and a compact PC
- Hosts: PH-K40 / PH-K01 (RK3588) and x86 PCs on Linux; driver and runtime in the system image
- VLMs and LLMs at the edge: models up to 7B in the card's 8 GB of memory
Typical uses: heavy model on the PH-K40 / PH-K01 · x86 PC on site: kiosk, industrial PC, operator workstation · VLM / LLM at the edge · test bench and development.
1. Purpose
When the host NPU is not enough — a heavy backbone, several models in a pipeline, a VLM — we add a card instead of replacing the device. The Axera AX8850 on an M.2 2280 card delivers 24 TOPS INT8 with 8 GB of its own memory, decodes up to 16 1080p streams by itself and stays within 7 W with a passive heatsink. It fits the PH-K40 (as a box option) and the PH-K01 (in place of the NVMe drive, with the system image on microSD), as well as an x86 PC with a free M.2 slot — a kiosk, an industrial PC, an operator workstation — running Linux. The model is converted to the card's format; the driver and runtime are already in the system image.
2. Platform
| SoC / accelerator | Axera AX8850 — 24 TOPS INT8 NPU, 8 Cortex-A55 cores on the card, 16×1080p video decoder |
|---|---|
| TOPS INT8 dense | 24 TOPS INT8 densemethod: Axera datasheet; FPS measured in the PH-K40 and in a compact PC enclosure — test bench |
| Memory | 8 GB LPDDR4x on the card |
| Storage | not applicable — uses the host's storage |
3. Interfaces
| USB | not applicable — cameras connect to the host (USB / MIPI / IP) |
|---|---|
| Ethernet / PoE | not applicable — host network |
| RS-485 / CAN / RS-232 | not applicable |
| GPIO / relay | none |
| M.2 | M.2 M-key 2280, PCIe 2.0 ×2 (works in PCIe 3.0 ×4 slots; in the PH-K40 — PCIe 2.1 ×1); 2242 form factor for the PH-K40 slot — made to order |
| Video output | none |
| Wi-Fi / BT / LTE | nonecard without radio modules — no FSB notification required |
4. Power and thermal
| Power input | 3.3 V from the M.2 slot |
|---|---|
| Power consumption (typical) | ≈4 W |
| Power consumption (peak) | ≤7 W |
| Cooling | passive heatsink; in the PH-K40 — thermal contact with the enclosure, in a PC — the PC's own airflow |
| 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 | 22×80×9 mm (M.2 2280, with heatsink) |
|---|---|
| Weight | ≈20 g |
| Mounting | standard M.2 screw |
| Connectors | M.2 M-key connector |
6. Environment and protection
| Operating temperature | 0…+60 °C (card datasheet); in a closed enclosure at +40 °C — test-bench measurement |
|---|---|
| Ingress protection | not applicable (inside the device or PC) |
| Vibration / shock | not applicable; in the PH-K40 — screw-mounted |
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.

8. Configuration options
| Option | Price |
|---|---|
| AX8850, 8 GB, heatsink — base | base |
| Installed and tested in the PH-K40 when ordering the boxordered as a PH-K40 box option | no surcharge |
| 2242 form factor / low-profile heatsink for the PH-K40 slotmade to order | made to order, price in the quotation |
| Installation in the PH-K01 (in place of NVMe, system image on microSD)made to order | made to order, price in the quotation |
Prices for 1 / 10 / 100 units and for options — in the quotation within 2 business days, valid 30 days. The contract includes a price revision formula tied to the Bank of Russia exchange rate and the DRAM index.
9. What's included
- Card with heatsink, M.2 screw, installation guide
- Card driver and runtime — in the PH-K40 / PH-K01 image; for x86 PCs on Linux — a driver package and a container
- Driver and runtime updates — together with the host image, from your network
- 1-year warranty, replacement card or spares; product passport (Russian regulatory data sheet); EAC declaration — in progress
10. Compatibility
| Cameras | host cameras: PH-Cam-K (USB) — on the PH-K40 and PH-K01, PH-Cam-M (MIPI CSI) — on the PH-K01; IP cameras (PH-Cam-S / PH-Cam-O) — the card itself decodes up to 16 1080p streams |
