More radios for your coordinator or hub.
A pocket-sized, self-powered USB expander for your SLZB coordinator or SMHUB hub. It turns one USB port into two powered outputs — run extra radios like a pair of SLZB-07 sticks, or click in a 4G/LTE or Z-Wave add-on. (It doubles as a 4G modem for a laptop, too.)

USB radios and modems are fussy about power, and a coordinator gives you just one port. The USB-Extender fixes both — its own power supply and two outputs in a box smaller than a matchbox.
A dedicated USB-C power input drives hungry devices without ever loading the host.
A full-size USB-A and a USB-C — run two more USB radios from a single upstream port.
Click in a 4G/LTE modem or a Z-Wave radio when a coordinator needs one.
A silent, fanless matte-black box that tucks in anywhere near your gear.

Give your coordinator more radios
A single-USB SLZB coordinator becomes a multi-radio setup. Run two more USB radios — say a pair of SLZB-07 sticks — from the powered outputs, or click in a 4G/LTE or Z-Wave add-on instead. Each output has its own clean power and the on-board CP2102 bridge keeps serial radios rock-solid. (The 4G module takes the internal bus, so in that setup it’s the one device.)

Fill your hub with USB gear
An SMHUB Nano or NanoMR is a full Linux hub, so there’s no coordinator limit — plug in as much USB gear as the outputs allow. Extra radios, a 4G/LTE uplink, storage, a Z-Wave stick — mix and match, each on its own clean power so nothing browns out.

Or a pocket 4G modem
Fit the 4G/LTE module, drop in a SIM and plug the USB-Extender into a laptop for mobile internet anywhere. Its own power input means the modem never browns out the laptop’s USB bus the way a bare dongle can.
Add a radio. Add the internet.

4G / LTE modem
Cat-1 mobile data with a nano-SIM slot and a u.FL antenna. Bring internet to any of the setups above.

Z-Wave radio
