Mikroe Brushless 7 Click is a motor driver based expansion board for controlling BLCD motors with any microcontroller. The board is based on the Toshiba TC78B009FTG IC three-phase BLDC motor controller that does not require Hall sensors. It features a built-in, closed-loop speed control function that regulates motor rotational speed under dynamic power fluctuations, and load variations. It eliminates the need for an external MCU for closed loop speed control with a precise setting of a speed profile done by the built-in nonvolatile memory (NVM). It's ideal for applications that include high-speed fans used in servers, blowers, cordless vacuum cleaners, and robot vacuum cleaners.
