In the era of Industrial Internet of Things (IIoT) and edge computing, CPU Modules serve as the "brain" of intelligent devices, directly defining the capability boundary of industrial systems. Diverse application requirements ranging from simple data acquisition to complex AI visual recognition cannot be addressed by a single one-size-fits-all core board solution. According to Statista 2026 industrial embedded computing market report, the global industrial CPU module market will reach $7.8 billion by 2027, with AI-integrated modules growing at a CAGR of 32% as edge intelligence adoption accelerates.

The E840-TTL (EC05-xxx) series is a compact, high-performance 4G CAT1 pin module designed for rapid IoT device integration. Measuring just 25×25 mm, this module enables bidirectional transparent data transmission between serial devices and network servers with minimal configuration. The 2.0mm pin header design simplifies integration into existing IoT projects, supporting both standard industrial voltage ranges and multiple network protocols.

EBYTE's embedded computing products serve diverse application areas, with clearly differentiated positioning between core boards and single-board computers to address varying customer requirements across the product development lifecycle.

EBYTE industrial computing product line, including the ECK10, ECK20, and ECK30 series core boards, addresses the growing demand for scalable embedded processing solutions that bridge traditional microcontroller (MCU) systems and high-end application processors.

In the high-precision positioning field, Real-Time Kinematic (RTK) carrier phase difference technology is the core foundation for achieving centimeter to millimeter-level positioning accuracy. However, RTK systems rely on stable, low-latency, highly reliable data links between base stations and rovers to transmit raw GNSS observation data or differential correction values.

In IoT project implementation, a seemingly simple requirement—"stable wireless communication from basement to 7th floor rooftop, 30m straight-line distance"—often becomes a critical bottleneck for system reliability

EBYTE's industrial computing division focuses on R&D of embedded computer core system products, which are different from traditional servers, desktops or laptops, and are embedded solutions for IoT

I2C (Inter-Integrated Circuit) is a two-wire synchronous serial bus that simplifies communication between microcontrollers and peripheral devices. Integrating I2C functionality into Bluetooth modules enables direct sensor data acquisition, external memory access, and peripheral control without additional host MCUs, reducing system complexity and BOM cost.

Based on 10+ years of industrial IoT deployment experience and over 10,000 real-world project cases, this guide provides systematic solutions for antenna configuration, helping you achieve communication performance close to or exceeding datasheet specifications.
