HS-100
New · the only cost-effective non-red switch board on the market
Ethernet Switch Board
The HS-100 is a compact four-port 10/100 Mbps Ethernet switch board built around the IC Plus IP175B integrated switch controller. Within a 42 × 42 mm footprint it delivers four independent 10BASE-T/100BASE-TX ports complete with on-board magnetics, so a full switching fabric can be embedded directly into a UAV, USV, robot or industrial enclosure without adding a separate switch module. The switch runs unmanaged straight out of reset using hardware strapping — no EEPROM required — and a host MCU can take full control at any time through the SMI header. A single wide-range 5–30 V DC input with reverse-polarity protection covers 2S–6S battery packs and 12 V/24 V vehicle rails directly. Designed, fabricated and assembled in Taiwan on a Taiwan/US/Japan semiconductor BOM.
