imp Hardware Options

How Electric Imp’s module choices compare

There are currently three hardware modules on the market that contain embedded Electric Imp technology: the imp003, imp004 and imp005. All three modules are fully compatible with the Electric Imp Platform and existing applications (with trivial modifications — see ‘imp Pin Mux’). The following table shows how these modules compare in terms of their size and the range of functionality they offer.

These modules include impOS™, which is provided by Electric Imp under license and is subject to a commercial software licensing fee that is not included in the module purchase price. For more detailed information on impOS licensing, please see ‘Commercial Software Licensing for Third-Party imp Modules’.

For information on ordering any of these products or becoming a distributor, please contact our sales team.
