221e is a technology firm, established in Italy.

Established in 2012, we have strengthen on each successful project assignment and today can count on the trust, partnership and repeat business of a number of valuable clients, from established multinational brands, to innovative startups.

221e can follow system development from concept to manufacturing; counting on solid enginnering skills, internal SMT assembly for rapid prototyping and an efficient network for supply chain along the whole process.

The value offered by 221e is built upon its technologies and knowledge: in algorithms modeling, in electronics engineering and product development. This is particularly true in the industries of IoT and wearables, where many different technical aspects and design constraints are to be fused in a common product platform.

With proprietary sensor fusion, 221e offers hardware designs and software libraries with accurate IMU and AHRS algorithms for inertial systems development and motion sensors applications.

Fields where 221e systems have found application are: Motorsports, Sport Science, Health/Biomed, Entertainment, VR and Personal Protective Equipment, Furniture, Automotive, Construction, and Industrial automation.
