Industrial 4G Dual-Ethernet IoT Edge Gateway & Telemetry PCBA
Overview:
Engineered for industrial automation, renewable energy monitoring (solar/wind telemetry), and smart grid power distribution, this compact, high-reliability gateway PCBA delivers robust edge computing and ubiquitous cellular connectivity. Driven by the Rockchip RK3328 Quad-Core 64-bit Cortex-A53 processor with dual SKhynix DDR3 RAM and Samsung eMMC flash, it seamlessly manages local protocol translation, data caching, and secure cloud transmission via dual Ethernet and 4G LTE Cat 1.
Key Manufacturing Capabilities & Highlights:
-
Quad-Core Processing & High-Speed Memory: High-yield SMT assembly of the Rockchip RK3328 BGA processor paired with dual DDR3 SDRAMs under strict impedance control, fully inspected via 3D AOI and 3D X-Ray for void-free solder joints.
-
Dual Isolated Ethernet Channels: Features dual RJ45 Ethernet ports backed by discrete Pulse H1102NL LAN isolation transformers, factory programmed and labeled with dedicated individual MAC addresses.
-
On-Board SIMCom 4G LTE Cat 1 Cellular: Precision surface-mounting of the compact SIMCom A7680C LCC wireless module, engineered with optimized 50Ω RF coplanar waveguide routing for superior cellular sensitivity.
-
Rugged Industrial Power & Optical Light Pipes: Wide-voltage DC power stage featuring a 100V-rated bulk capacitor and heavy-duty power chokes to handle harsh electrical environments. Pre-fitted with four vertical optical light pipes (Red, Orange, Green, Yellow) for front-panel enclosure status indication.
-
Full Turnkey Quality & Traceability: Automated laser-etched 2D Data Matrix code and barcode tracking, 100% in-circuit testing (ICT), MAC ID flashing, and comprehensive functional communication validation.
