Frequently Asked Questions

Q: What power supply does the 4-port embedded Ethernet switch module require?

A: The module accepts a wide DC input voltage of 5V to 12V at 1A, delivered via a 2-pin terminal with 2.5mm pin spacing. This makes it compatible with a wide range of embedded system power supplies, USB power converters, and standard DC adapters.

Q: Can I use this mini Ethernet switch module with a Raspberry Pi or Arduino-based project?

A: Yes. Its compact 50 × 45 × 11 mm form factor, low power requirement (DC 5–12V), and 4-pin 2.5mm pitch connectors make it well-suited for integration with Raspberry Pi setups, Arduino shields, and other single-board computer projects that require multiple wired Ethernet connections.

Q: Does this switch support full duplex operation?

A: Yes. Each port supports both half and full duplex operation. Fast Ethernet ports operate at up to 100 Mbps half duplex or 200 Mbps full duplex, and the module complies with IEEE 802.3X flow control for reliable data transmission.

Q: What cable type is required for this embedded switch module?

A: For 10Base-T connections, use UTP Cat 3 or higher cables (up to 100m). For 100Base-TX Fast Ethernet connections, use UTP Cat 5 or higher cables (up to 100m).
