2026-03-22 20:08
Trxcom, a global professional provider of network connector and magnetic component solutions (Huizhou Trxcom Electronics Co., Ltd.), has entered into a deep technical cooperation with the UK-based Raspberry Pi Foundation. Its TRJG0926HENL4R integrated network transformer RJ45 connector (MagJack), with outstanding gigabit transmission performance, high reliability and broad compatibility, has officially become the core supporting network port component for the Raspberry Pi 4B series single-board computers.
I. Raspberry Pi: A Benchmark in the Embedded and Maker EcosystemRaspberry Pi is a compact single-board computer (SBC) developed by the Raspberry Pi Foundation in the United Kingdom. With its core advantages of low cost, high integration and strong expandability, it is widely used in maker education, embedded development, Internet of Things (IoT), industrial control, lightweight servers and other scenarios, and has become a benchmark product in the global microcomputing ecosystem.
Taking the Raspberry Pi 4B as an example, it is equipped with a 64-bit quad-core ARM high-performance processor, up to 8GB of large memory, dual HDMI 4K output, multiple specifications of USB interfaces, dual-band WiFi and Bluetooth, with comprehensive hardware expansion capabilities. At the same time, it is natively equipped with gigabit Ethernet and compatible with IEEE 802.3af PoE power supply, enabling integrated deployment of data and power transmission via a single network cable, which greatly simplifies on-site wiring.
Relying on its complete hardware configuration and open-source ecosystem, Raspberry Pi can be used to build home NAS, intelligent gateways, data acquisition terminals, robot control devices, etc., and is a key hardware carrier connecting IoT terminals and network transmission.
II. Gigabit Ethernet Port: The Core Cornerstone of High-Performance Raspberry Pi ApplicationsAmong various external interfaces, gigabit Ethernet is the core of the Raspberry Pi to achieve high-speed, low-latency and stable transmission, with particularly prominent value:
Superior Performance Over Wireless: The actual throughput of the gigabit Ethernet port can reach 940Mbps, which is more than 5 times the bandwidth of ordinary 5G WiFi. It is free from signal interference and has lower latency, making it an essential configuration for file storage, cluster services and high-definition transmission.
PoE for Minimalist Deployment: It supports remote power supply via network cable, no external power supply is required, which is suitable for power-free scenarios such as outdoor monitoring and industrial points, reducing wiring costs.
Industrial-Grade Stable Operation: The physical wired connection has strong anti-interference ability, supports wake-on-LAN, and can meet the demand for 7×24-hour uninterrupted stable operation of equipment.
The core product of this cooperation, TRJG0926HENL4R, is an integrated MagJack RJ45 with transformer customized for gigabit Ethernet. It is precisely compatible with the RTL8211F gigabit PHY chip built into the Raspberry Pi 4B, laying a solid hardware foundation for the network performance of the equipment.
