GSM module
One of the possible optional accessories is a GSM module for your project, whether for a WEBserver or Remote-Start solution. The native connectivity of both devices is wired, but with this extension, you can easily connect them to an LTE/GSM network.
You insert the GSM module into one of the conveniently located USB ports. Then, the device performs all the settings to ensure a successful LTE/GSM network connection.
