Brushless 3 click carries the DRV10983, a three-phase sensorless motor driver with integrated power MOSFETs. When an external power supply is applied, you can drive a brushless DC motor through the PWM pin, AN pin or I2C interface. It communicates with the target microcontroller over I2C interface, with the additional functionality provided by the following pins on the mikroBUS™ line: PWM, AN, INT, RST.
Brushless 6 click is designed to drive a three-phase sensorless, brushless motor, also known as the BLDC motor. The motor rotation is controlled by receiving driving commands via the incoming PWM signal. This click board fully controls the rotation of the BLDC motor by utilizing the onboard MCU ATmega8A, an 8-bit MCU from Microchip. The onboard MCU outputs are not adequate to power on the coils of the BLDC motor directly, so this MCU is used to control the power circuitry, instead. This circuit consists of 6 MOSFET transistors, used to switch the power from an external power source to the appropriate stator coils.
The advantages of the BLDC motors over the other types of DC motors are many. Thanks to their contactless design, BLDC motors last longer and because of the superior rotational speed and torque properties, BLDC motors are widely used for high-speed, lightweight applications such as the drive motors for drones, electronic cooling equipment, small house appliances, robotics and similar applications. The Brushless 6 click provides an easy and elegant solution for driving BLDC motors.
DC Motor 8 click is a DC motor driver. It can drive simple DC motors with brushes, providing them with a significant amount of current and voltage up to 40V. The click has one control input, that uses the PWM signal from the host MCU. It uses the half-bridge topology to regulate the speed of the motor rotation, employs advanced dead-time circuitry that monitors the output stage, providing maximum switching efficiency and features an advanced technique to avoid shoot-through currents.
Features, such as high-efficiency factor, low overall power consumptions and complete isolation of the output stage, enable this device to be used in various battery operated handheld tools, fans and in general - whenever a powerful and reliable DC motor driver is required.
Stepper 7 click is a bipolar step motor driver. It features an H-bridge bipolar step motor driver, which supports full and half step control modes. Stepper 7 click also carries a port expander so that the communication can be done with a minimal number of pins, through the mikroBUS™ SPI bus.
Stepper 7 click offers thermal protection, integrated kickback voltage protection, it has a wide range of input voltage, protection against current shoot-through the H-Bridge and reasonably high current capability. These features make Stepper 7 click an ideal solution for driving motors in any application that demands a precise and safe step motor driver.
