Introduction The Freedom development platform is a set of software and hardware tools for evaluation and development. It is ideal for rapid prototyping of microcontroller-based applications. The FRDM-MC-LVBLDC low-voltage evaluation board, in a shield form factor, effectively turns a Freedom development platform into a complete motor control reference design, compatible with existing Freedom development platforms, FRDM-KV31F and FRDM-KV10Z, and the low-cost motor FRDM-MC- LVMTR. The FRDM-MC-LVBLDC shield board implements a 3- phase Brushless DC (BLDC) interface platform that adds BLDC motor control capabilities, such as rotational or linear motion, to your design applications.
