Today in Edworking News we want to talk about Networking Switch Outline: The mrxSwitch is the world's smallest and cheapest networking switch, in addition to being fully open-source. With a focus on simplicity and cost, the MUREX Ethernet Switch utilizes external magnetics, a high-performance unmanaged switch IC, and 1.25mm pitch Fast Ethernet (100BASE-TX) connectors.
Detailed Description
The MUREX Ethernet Switch, or mrxSwitch, is a 5 port 100BASE-TX unmanaged switch using the IP175Gx Ethernet Integrated Switch IC. mrxSwitch can step down an input voltage of up to 15V to its operational voltage of 3.3V.
Designed with a four-layer board for minimal noise, the mrxSwitch has full Bob-Smith style termination for all center taps and calculated differential pairs of 100Ω. The switch utilizes 10 pairs of magnetic transformers and common-mode chokes to ensure proper compliance with the IEEE 802.3 standard.
Measuring 44.9mm by 42.2mm, mrxSwitch V2 is the smallest networking switch in the world and significantly outperforms all commercially available options in size and cost.
Applications and Use Cases
mrxSwitch can be used in various scenarios, including but not limited to:
Embedded systems
ROVs (Remotely Operated Vehicles) and AUVs (Autonomous Underwater Vehicles)
Consumer electronics
DIY projects
Other space-constrained networking applications
Current Status and Integrated Sensors/ICs
The mrxSwitch integrates the following sensors/ICs:
IC Plus IP175Gx (5 Port 10/100 Ethernet Integrated Switch)
LM1117MP-3.3 (800mA Low Dropout Regulator)
QT48A03 (1000Base-T Dual Port Transformer)
BT16A07 (10/100 Base-T Single Port Transformer)
2x QT24A23 (retired) (10/100/1000Base-T Single Port Transformer)
All components are meticulously chosen to ensure it meets high-performance standards without compromising its compactness and affordability.
