PCB version 4G industrial router

In the rapid evolution of the Industrial Internet of Things (IIoT) and smart manufacturing, the demand for lightweight, miniaturized, and highly integrated devices has become a key industry trend. Shenzhen Huizhi Technology’s newly launched WIS903 lightweight 4G industrial gateway, with its innovative PCB-mounted form factor and compact design, offers a more flexible deployment solution for industrial scenarios—especially where installation space is limited.

▶ I. Core Advantages of WIS903: Compact Size, Powerful Features

Traditional industrial gateways are typically housed in standalone enclosures, resulting in larger sizes that restrict installation in tight equipment cabinets or embedded environments. WIS903 breaks this limitation by providing, in addition to conventional integrated installation, a direct PCB-mounted version. This reduces size by more than 50%, significantly lightens weight, and enables seamless integration into various industrial devices, all while retaining full 4G communication and data processing capabilities:

  • Ultra-compact design: By using highly integrated components and optimized layout, the PCB version is over 50% smaller than traditional gateways, making it ideal for embedding in PLC cabinets, motor control boxes, or mobile devices.
  • Industrial-grade performance: Supports full 4G connectivity, Ethernet, and Wi-Fi. Built to industrial standards, it operates reliably across wide temperature ranges and in environments with electromagnetic interference.
  • Flexible integration: PCB interfaces allow users to customize connections as needed, easily integrating with other modules for seamless system design.

▶ II. Why Is the PCB Version Preferred?

Flexible Installation

The PCB version can be soldered directly or fixed via standard slots onto the customer’s main PCB, eliminating the need for external enclosures and saving valuable space. This is particularly suited for applications sensitive to size, such as smart meters, AGVs, and micro industrial computers.

Cost Optimization

By omitting the enclosure and standalone power modules, the bill of materials (BOM) cost is reduced. Customers can also perform secondary development and customize peripheral circuits according to their needs.

Simplified Heat Dissipation and Maintenance

The board-mounted design helps heat dissipate through the device’s overall structure. Its modular architecture also supports quick replacement, reducing downtime.

▶ Conclusion

The PCB version of the WIS903 exemplifies Huizhi Technology’s customer-driven innovation philosophy, delivering a cost-effective and easily integrated communication solution for Industry 4.0 scenarios. In projects where space and budget are constrained, this gateway is poised to be an ideal alternative to traditional solutions. As industrial devices continue to miniaturize, such highly integrated designs are likely to become a new industry standard.
