Frequently Asked Questions
Q: What voltage does this 3-port Gigabit Ethernet switch module require?
A: The module accepts a wide DC input range of 5V to 12V at 1A, delivered via a 2-pin terminal with 2.5mm spacing. This makes it compatible with most common embedded and single-board computer power supplies.
Q: Can I use this switch module with standard RJ45 cables?
A: The module itself uses 4-pin 2.5mm pitch connectors designed for direct PCB or embedded integration rather than standard RJ45 jacks. You can wire RJ45 breakout adapters to the pin headers for use with Cat5/Cat5e/Cat6 patch cables in your custom build.
Q: Does this Gigabit Ethernet module support auto-negotiation and full-duplex?
A: Yes. The module is IEEE 802.3 / 802.3u / 802.3X compliant, supporting 10/100/1000 Mbps auto-negotiation and full-duplex operation with flow control on all three ports.
Q: What is the maximum throughput (backplane bandwidth) of this switch module?
A: The backplane bandwidth is 1 Gbps, with a forwarding rate of 1000 Mbps using store-and-forward switching — suitable for high-speed data transfer in compact embedded network designs.
