A few weeks ago, Raspberry Pi launched a new official WiFi dongle with the following specs 802.11 b/g/n; USB 2.0; BCM43143 chipset; 150Mbps maximum throughput.

A polyfuses will have as much as 0. A limit. As a consequence the USB ports are only directly suitable for . Not only do non single current unit devices draw more current (causing greater Voltage drops, and greater stress on the fuses), they also might require 4. Volt to work. Users should still ensure their power supply can power the Raspberry Pi and the USB peripherals. Revision 2. 0 was released in August 2. Warning: Because the polyfuses have been removed, back feeding of the PI, by applying power via its normal USB output, can damage D 1. This can be discovered by melts, scorching, smoke or worse. These included problems with USB 1. Kinect) and the way the ARM processor handles the SMSC9. See RPi Powered USB Hubs.

There are some interfaces that are supported in Linux while they do not comply to the standards because specific quirks have been added to the USB Linux drivers. To verify if your interface is supported search for a manual of your interface and check if it needs drivers to run under Windows/Mac. If the manual explicitely mentions no drivers are needed the interface is almost surely a class compliant device. When in doubt check the aforementioned databases.

Pi. TVA few weeks ago, Raspberry Pi launched a new official Wi. Fi dongle with the following specs. This makes it a little longer than the other two, but how does it stack up against them in terms of performance? That’s what we’re here to find out. Inside the RPi Wi. Fi dongle, showing the large antenna. I spent quite some time testing all three different USB wifi dongles that I own. This should give me different signal strengths. So I got out my trusty Nexus 5 phone, fired up Wi. Fi analyser, and scouted out various locations around the house and garden. A Wi. Fi Analyser scan near to the router. We’re in a house with thick internal brick walls and solid reinforced concrete floors at the moment. The router is on the first floor at Ras. Pi. TV Polska HQ. My phone told me I had a signal strength of. This is quite important because the orientation of the dongle can make a large difference to the reported signal strength. I wanted all the results to be truly comparable. You can test this with your phone and Wi. Fi Analyser. If you flip it from horizontal to vertical, I can almost guarantee you’ll get a change in signal strength. I used my e. Meter (which has a calibrated shunt and measures current to two decimal places) to measure the voltage and current during the various tests. I used a Raspberry Pi 2 model B, connected to an HDMI screen and a USB keyboard dongle. This was powered by a lipo and regulator connected via the e. Meter’s shunt. Current measurement setup for wifi dongles. A blank baseline value of voltage and current consumption with no Wi. Fi dongle attached was measured. The Wi. Fi signal strength was measured using my Nexus 5 and Wi. Fi Analyser. For each dongle, in each location, I went through the following procedures. Baseline Measurements. Starting with power off, insert wifi dongle in top right USB port. Power on. Login and Start LXDE startx. Open Epiphany browser and browse to the Ras. Pi. O GPIO Ruler KS page. Open LXTerminal. Wait for current reading to stabilise. Read Vidle and Iidle – the idle voltage and current. Scanning For Wi. Fi Networks. Scan for Wi. Fi networks using this command in LXTerminal sudo iwlist wlan. VWi. Fi and IWi. Fi peak current during the scan. This was done three times. Output from a Wi. Fi scan. For each of the above scans, the reported signal strength and quality was noted. The Edimax dongle, unfortunately, gave a different set of results (different drivers?) so may not be directly comparable for this test. The other two gave signal strength readings (in d. Bm) and an indication of signal quality x/7. Browsing and You. Tube Streaming. Then we browsed to the Ras. Pi. TV Youtube channel in Epiphany and noted the peak current while that, “fairly busy” page was loading, this was labelled Iytp (ytp = You. Tube Peak)Then the Ras. Pi. O Duino Tutorial #2 video was selected and allowed to play for a minute or so. This was used to measure the stable current during sustained heavy internet use Iyts (yts = You. Tube Stable) which was usually a range spanning about 0. A. What About The Results? A few preliminary comments. I was using a freshly flashed SD card with the latest Raspbian and was delighted to find that all three dongles worked perfectly straight out of the box. All I had to do was tell the Pi the wifi access point password (just once) and thereafter, connection was completely automatic. That was delightful, and shows how far the software side of things has come. Edimax was my favourite wifi dongle for a long time because it had the lowest power consumption in my tests. All three dongles worked well enough, out of the box, to be able to stream Youtube videos acceptably in the basement, where the weakest connection was made. So in terms of usability, there was nothing between them. I’ve never done range testing before, but one interesting thing to come out of these tests was the Workshop tests, which I didn’t tabulate. Simply because none of the devices could connect that far out. My Nexus 5 could “see” the wifi router and reported - 8. Bm signal strength. The Official Raspberry Pi dongle could also “see” the router and reported - 8. Bm strength and 2. But neither of them could connect in that location. Having said that, neither The. Pi. Hut nor Edimax dongles could even “see” the router in that location. So there’s no doubting that the RPF dongle has better range, but I have yet to be able to quantify it in a useful way. So Where Does That Leave Us? If you look at the power consumption data, Iidle, IWi. Fi and specifically Iyts you can see that the official Raspberry Pi dongle has more or less the same power consumption as the Edimax, but remember its slightly better range. The. Pi. Hut dongle consistently uses about 4. A more than the other two. This is not a lot, but if you’re running from batteries, it all counts and could be an issue in some applications. What Else Should We Consider? Well there’s always the cost isn’t there? Both the offical Raspberry Pi Wi. Fi dongle and The. Pi. Hut dongle are . Perfect for Raspbian. The. Pihut Wi. Fi dongle – good price, good performance for most applications. Supported by most Pi OSes. Edimax Wi. Fi dongle – good power consumption, good performance for most applications, but the others make it start to look expensive – it also has its own, non- standard way of reporting signal strength, which has annoyed me in this testing process. It seems that the Swag Store is out of stock of the official dongles at the moment, but The. Pi. Hut also sells these official dongles (in fact Jamie gave me the one I have for testing) and does currently have stock at.
