Freescale Semiconductor, Inc. User's Guide Document Number: FRDMLVBLDCUG 0, 02/2016 Freedom FRDM-MC-LVBLDC Development Platform User’s Guide 1. 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-MCLVMTR. The FRDM-MC-LVBLDC shield board implements a 3phase Brushless DC (BLDC) interface platform that adds BLDC motor control capabilities, such as rotational or linear motion, to your design applications. © 2016 Freescale Semiconductor, Inc.
