The YoctoHub-Wireless is a wireless-enabled module that can host three Yoctopuce modules to access them remotely through a Wifi network. It can be powered either by a USB Micro-B cable and a regular phone charger, or a 5V battery pack.
The YoctoHub-Wireless can be used in the same way as a VirtualHub running on a little PC, but it is much easier to setup and maintain than a PC. It smaller and consume less. It is compatible out-of-the-box with all existing applications using Yoctopuce API. As for the VirtualHub, it can run autonomously using HTTP callbacks.
Moreover, the YoctoHub-Wireless features a built-in clock timer, that makes it possible to put the device into low-power deep sleep and wake-up automatically at predefined time. This makes it possible to reduce power consumption to 15uA while sleeping, which is crucial for applications running on battery or solar panels. The YoctoHub-Wireless only needs a few seconds of wake-up time to post data on an web server using the HTTP callback.
Three Yoctopuce modules can be connected directly, one of which can be fixed directly on the YoctoHub-Wireless and connected using a Board2Board-127 connector. More devices can be connected thanks to the YoctoHub-Shield extension. The YoctoHub-Wireless can power Yoctopuce devices up to 2A.
The device is provided with an articulated antenna (9cm, with RP-SMA connector) and a connection cable (uFL to RP-SMA). The use of a real antenna, and the fact that this device uses the 802.11b standard (slower but more robust than the faster variants) make it possible to connect to an access point from significantly farther than what most mobile phones and tablets can achieve.
Warning: although the 3 downstream ports hosting Yoctopuce devices use USB micro-B connectors, the YoctoHub-Wireless use a specific protocol simpler than USB to talk to the devices. Therefore, it is not possible to drive or even to power a regular (non-Yoctopuce) device using the YoctoHub-Wireless. It is not possible neither to use a regular USB hub (such as the Micro-USB-Hub) on the downstream ports. If you need more downstream ports for Yoctopuce devices, you can use a YoctoHub-Shield.
The YoctoHub-Wireless is replaced by the YoctoHub-Wireless-g, and not anymore stocked. We can however still build it for volume orders.
USB cables and enclosure to be ordered separately.
This would be perfect to create autonomous devices that just need access to power, without having to hook them up to a mini pc to run them. Would definitely love to see this come out of vaporware.
We have are currently tracking a few last firmware issues in the Yocto-MeteoWireless and YoctoHub-Ethernet. The YoctoHub-Wireless will come straight after, but it is not so far anymore...
What about Yocto-MeteoWireless today? It is very very interesting!
You mean this one?
We will ship beta-test units shortly... drop us a note :-)
Sorry! It is my English.. I mean, when i can buy this device.
Is it possible to be alerted when it will be available ?
Yes, just drop an email to support mentioning the product you are interested in
Hi, can't wait for this to be released!
How will this board be powered? What is the power consumption?
Do You think low power RF communication (like ZWave) will be surclassed by Wifi?
What wifi standard/speed will You support?
It will 5V powered through the USB connector. So any USB charger or USB solar battery suit it. Consumption will be around 150mA in operation. But there will be a deep sleep mode. In that mode, consumption will be less than 1mA. The device will be able to wake up from deep sleep at specific time or when an external signal occurs.
I don't think low power communication and WiFi are competing. They both have advantages and disadvantages. We chose WiFi because almost everyone have a WiFi infrastructure at his disposal.
The device will support 802.11b at least. We have some plans for 802.11g but tests at still ongoing.
Hi thank you for the answers!
I think it would be awesome to have something like in Zwave or other protocols, to create a mesh in a way that if I have more Yocto wireless devices I need 1 device of these which acts as a master "gateway" and which I can manage in my network giving only one IP address; the other Yocto devices speak with this master device in a private Yocto network and when I need to talk to these devices I ask to the master gateway only; in this way I need to know only 1 IP address and I don't have to worry about implications in an already existing network (number of IP addresses, wireless networks can cause big security flaws for enterprise networks, etc.).
Look for example at this solution (very innovative):
All the lamps speak together and You have to select only 1 master to manage all the others and send/receive commands; obviously the next step would be to have a main and backup device so that I don't lose all my sensors when the master gateway dies.
What do You think?
Indeed this is very interesting, but we have no immediate plans for low energy wireless devices. Right now, our top priority is releasing the Ethernet and Wifi devices :-)
Can I use this device as a USB hub also? I want to connect it to a computer directly on the usb downstream connector, and wireless at a later stage. thanks.
@Ryan Benson: No, you cannot to control Yoctopuce devices directly from the upstream USB port of the YoctoHub-Wireless: only the hub logic is available from there. However, just use a regular USB hub and run a VirtualHub on your computer, and this will behave just as you planned. The YoctoHub devices and the VirtualHub software behave the very same way.
