Revision History ................................................................ 4 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. 2016 Freescale Semiconductor, Inc.

FRDM-MC-LVBLDC Hardware Overview The features of the FRDM-MC-LVBLDC hardware are as follows: Power Supply Input voltage DC: 10-15 V DC via 5.5x2.1mm barrel connector. Output current up to 5 amps RMS. Power supply reverse polarity protection circuitry. 3-phase bridge inverter (6- MOSFETs). 3-phase MOSFET gate driver with over current and under voltage protection. Analog sensing (DC bus voltage, DC bus current, 3-phase back-EMF voltage). 5.5 V DC auxiliary power supply providing FRDM MCU board supplying. Motor speed/position sensors interface (Encoder, Hall). Freedom motor control headers compatible with Arduino R3 pin layout. The FRDM-MC-LVBLDC board does not require any hardware configuration or jumpers setting. It contains no jumpers.
