Colswe-Hub-GSM-3G-EU is a wireless-enabled module that can host three Colswe 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 900 MHz and 1800 MHz used in Europa, Middle-East, Africa, Asia and Pacific. For a detailed list of frequency bands supported in each country, please refer to the Wikipedia page GSM_frequency_bands
Colswe-Hub-GSM-3G-EU 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.
Furthermore, Colswe-Hub-GSM-3G-EU 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. Colswe Colswe-Hub-GSM-3G-EU only needs a few seconds of wake-up time to post data on an web server using the HTTP callback.
Three Colswe modules can be connected directly, one of which can be fixed directly on Colswe-Hub-GSM-3G-EU and connected using a Board2Board-127 connector. More devices can be connected thanks to the YoctoHub-Shield extension. Colswe-Hub-GSM-3G-EU can power Colswe environmental 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 Colswe environmental devices use USB micro-B connectors, Colswe-Hub-GSM-3G-EU uses a specific protocol simpler than USB to talk to the devices. Therefore, it is not possible, neither to drive or even power a regular (non-Colswe environmental) device using Colswe-Hub-GSM-3G-EU nor to use a regular USB hub, such as the Micro-USB-Hub on the downstream ports. If you need more downstream ports for Colswe environmental devices, you can use a YoctoHub-Shield.
