Product Datasheet

Key Features

4-port USB 3.0 hub using JST GH locking connectors — mechanically retained, vibration-immune contacts
Fully USB 3.0 protocol-compliant; plug-and-play, no external driver required
Designed for companion computers on drones and mobile robots where standard USB connectors fail under vibration
All connections use locking GH crimp connectors — no accidental disconnection in field deployments
ESD protection on all USB ports
Optional USB Power Delivery (PD) input: requests higher voltage from a PD charger when bus power is insufficient
Per-port overcurrent protection with hardware safety switch
Dual power inputs: USB upstream port (PD model) and 2.54 mm pin header (5–28 V / 7.5 A / 60 W max)

⚠ If USB 3.0 communication is unstable, remove the upstream SM08B / downstream SM08B connector and solder the wires directly to the pads. Use USB 3.0-rated twisted shielded cable with 90 Ω controlled differential impedance. Maintain consistent twist pitch and keep untwisted length at terminations to a minimum. Connect the shield to GND at one end only. Keep cable length as short as possible.

ⓘ SM connectors are included in the package but shipped unsoldered. Soldering is required before use. Note that SM connectors are not optimized for high-speed signal integrity; direct wire soldering to the pads is strongly preferred when operating in USB 3.0 mode.
