• YoctoHub-Wireless-SR

The YoctoHub-Wireless-SR is a wireless-enabled module which can host three Yoctopuce modules to access them remotely through a WiFi network. It can be powered either by a Micro-B USB cable and a regular phone charger, or a 5V battery pack.

You can use the YoctoHub-Wireless-SR in the same way as a VirtualHub running on a little computer, but it is much easier to setup and maintain than a computer. It is smaller and consumes 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-SR 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-SR only needs a few seconds of wake-up time to post data on a web server using the HTTP callback.

You can connect three Yoctopuce modules directly, one of which can be fixed directly on the YoctoHub-Wireless-SR and connected using a Board2Board-127 connector. More devices can be connected thanks to the YoctoHub-Shield extension. The YoctoHub-Wireless-SR can power Yoctopuce devices up to 2A.

Contrarily to the YoctoHub-Wireless, which looks very similar, this version does not include an antenna connector but uses a tiny antenna directly integrated on the PCB. It takes less space, but should only be used in applications when there is a good wireless connectivity, away from any strong electromagnetic interference.

Warning: although the 3 downstream ports hosting Yoctopuce devices use micro-B USB connectors, the YoctoHub-Wireless-SR uses 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-SR. It is not possible either 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.
