Roll over image to zoom in

The TWR-K21D50M module is a development board for the Kinetis® K11, K12, K21 and K22 MCUs, which are ideal for optimized, cost-sensitive security applications.

This Tower® module is designed to enable rapid prototyping and development for applications requiring medium embedded memory densities, security through tamper detect and crypto unit and communication through USB.

The TWR-K21D50M module operates as a standalone debug tool and can also be combined and used as part of the modular Tower System development platform..
