NE-4120 Series/NE-4120-ST
NE-4120 Series modules are very similar to NE-4110 Series modules. The main difference is that
NE-4120 Embedded Network Enablers are pin header type. NE-4120 Series has 2 models:
NE-4120S and NE-4120A, both of which measure 57 × 40 mm.
NE-4120-ST is the testing and evaluation board that can be used with the two NE-4120 Series
embedded modules.
