The YoctoHub-GSM-3G-NA is a wireless-enabled module that can host three Yoctopuce modules to access them remotely through a 3G GSM cellular network (UMTS and HSPA). It can be powered either by a USB Micro-B cable and a regular phone charger, or a 5V battery pack.

The radio module supports the two GSM frequency bands 850 Hz and 1900 MHz used in North-America, Caribbean and Latin America. For a detailed list of frequency bands supported in each country, please refer to the Wikipedia page GSM_frequency_bands.

The YoctoHub-GSM-3G-NA 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-GSM-3G-NA 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-GSM-3G-NA 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-GSM-3G-NA and connected using a Board2Board-127 connector. More devices can be connected, thanks to the YoctoHub-Shield extension. The YoctoHub-GSM-3G-NA can power Yoctopuce devices up to 2A.

The device is provided with an articulated antenna (9cm, with SMA connector) and a connection cable (uFL to SMA).

Warning: although the 3 downstream ports hosting Yoctopuce devices use USB micro-B connectors, the YoctoHub-GSM-3G-NA 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-GSM-3G-NA. 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.
