It is an ideal way to prototype a motorcontrol project or simply explore motor-control functionality. It supports control of brushless DC (BLDC), brushless AC (BLAC), stepper, and dual-brushed DC motors. The main board has two full H-bridges, so up to four phases can be controlled with up to 100% duty cycle. Phase voltage, as well as in-phase current can be measured on three phases, and virtual ground voltage and common low-side current can be measured, too. For safety and protection, there is an input over-current trip protection. When the motor is generating power the actively controlled breaking circuitry becomes enabled, and above a certain bus voltage level the circuit breaks  automatically. For design flexibility, there are several communications interfaces, including USB, Ethernet, CAN, RS-422/485, and a UART-to-USB bridge. The board also has a small graphic user interface (96x64 pixel OLED) with a joystick, to allow for simple, intuitive human interaction. The kit is available through NXP’s distribution partners.
