SpecPicks Verdict
SpecPicks scored Smays Micro USB OTG to Ethernet Adapter with Powered Hub using a rating × review-volume × price-fit model applied to published specs and reviews across the single board computers category. Smays's single board computers lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for single board computers of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Does the Smays OTG Ethernet adapter work with a Raspberry Pi Zero?
Yes. The listing names the Raspberry Pi Zero, which has a micro-USB OTG port, and also lists the Raspberry Pi 2. You get 10/100 Mbps Ethernet plus 3 USB 2.0 ports on the Pi.
Will the adapter power or charge my Fire TV Stick, Chromecast or tablet?
No. The built-in 5V DC port powers only the USB 2.0 hub and charges the devices plugged into it. It does not power the host device, so keep that device on its own power supply.
How do I know if my Android phone or tablet is compatible?
Android support is limited. Open Settings and look under Wireless & Networks for a grayed-out Ethernet menu. If it is there, the adapter will most likely work. Android 6.0 or later is listed as driver-free.
How fast is the wired connection?
The Ethernet port runs at 10/100 Mbps. It does not support gigabit speeds. That is enough for streaming and general browsing, but it is slower than a gigabit adapter on a fast internet plan.
Do I need to install drivers on my computer?
No. It works without drivers on Windows 8.1 and 10 (32/64-bit) or later, macOS 10.9 or later, Android 6.0 or later, and Chrome OS. For other operating systems, check the product listing.
