  ==== Neuron S103-G ====
  The Unipi Neuron S103-G unit is equipped with the Quectel M66 GSM/GPRS module and a MiniSIM card slot. This allows the unit to connect to a GSM network and sending notifications, or status messages, or receiving requests via SMS. If properly configured, it is also possible to use GPRS to connect to the Internet.
