Brushless 4 click is a 3 phase sensorless BLDC motor driver, which features a 180° sinusoidal drive, providing high efficiency and low acoustic noise. This type of drivers inherently provides higher torque in general, compared to classical 120° BLDC motor drivers. Brushless 4 click allows a wide voltage range to be used for the power supply: from 2V, up to 14V. The Click board™ features a standard set of protection features: overvoltage protection, overtemperature protection, overcurrent limiting, but also some more specific protection features, such as the rotor lock-up protection and automatic restart function.

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.
