Fan-Less 1U Rackmount Network Appliance NK02 Series - High-Performance Intel Atom C3000, China Suppliers and Factory
Product Features
Decent Performance
The processor features an integrated SoC design, bringing efficient intelligence to the network edge.
SKU of C3338R/C3558/C3758 from 2 to 8 Cores, with TDP ranging from 10.5 to 25W, suitable for power-optimized network security devices.

Consistent Quality
Comparing to C236 Chipset platform, NK02 offers similar performance but more consistent quality.
Two hardware watchdogs are designed, one of which is via super I/O, the other one is via MCU to achieve bypass control.

Highly Configurable
eMMC/mSATA/SATA/M.2 SATA, with IoT/AI/dual-SIM cards, 4G/5G LTE, Wi-Fi 5/6 modules, etc.
Commercial-grade, wider temperature range.
1U rackmount style comes with one power button, and configurations of single/dual/redundant PSU.
