Features:
1. Product performance is good, multi-functional, almost all small motors with Hall can be driven stably, the board comes with a potentiometer speed control, support for change to external potentiometer speed control
2. This drive for small power fan brushless Hall drive, can also be done in other systems embedded, specifically for small space and small power DC three-phase brushless motor air pumps, water pumps, oil pumps, fans, etc. and industrial control electric gadgets, etc.
3. The drive humanized design, interface using terminal blocks, with free Hall lead wires, integrated speed potentiometer on the board
4. Supports a wide voltage input range of 6V to 24V, suitable for a variety of power systems, improving the flexibility and convenience of use.
5. Provide clear wiring instructions and adjustment guide, user-friendly design makes the installation and parameter adjustment easy and fast.

Parameter:
Product name: three-phase DC brushless with Hall drive
Operating voltage: 6-24V (limit 28V)
Driving current: rated 3.5A peak 4A
Current limiting and stalling protection: current exceeding 4A current limiting protection, motor stalling and keeping 5 seconds shutdown protection.

Interface description:
1, ABC phase line output, connected to the motor
2、VCC GND main power supply (external DC power supply)
3, PWM external duty cycle speed signal input (PWM signal amplitude 3-5V frequency 1KZ-20KHZ) This interface supports the connection of 5V full-speed operation, grounding stop operation
4, FG speed pulse signal output (only leave the interface)
5, DIR forward and reverse control interface (low-level effective, can be connected to the ground external switch)
6、BRAKE brake control interface (low-level effective, can be connected to the ground external switch)
7, Ha Hb Hc +5V GND Hall signal, power supply input interface, general motor with Hall have the corresponding 5 lines

Notes:
1, the motherboard power supply circuit without a fuse, it is recommended to add their own, the power supply positive and negative polarity reversal will cause permanent damage to some of the chips on the board (that's not even 1 second)
2, the normal operation of the motor blocking protection, please do not artificially short-circuit the module is not working properly, but short-circuit has burned the line burst tube may be the first time to try the wiring, please use a small current and low voltage test, please match with the voltage, current and power of the equivalent of three-phase DC brushless Hall motor to use (this module is a smaller power overload capacity of the use of the weak to leave a margin for the use of the motor can not be connected to the work of the high-power motor or the test machine)
3, the module power is small (maximum 100W) overload capacity is weak when using the use of spare capacity, can not be connected to high-power motor work or test machine, forced to work with the risk of impact damage to the power tube, it is recommended that the use of power 12V power supply 42W 24V power supply within 84W
4, do not connect the obvious and drive module voltage current power phase does not match or far from the motor, to avoid inexplicable damage!
5, due to the forward and reverse is no delay hard commutation, as well as high-speed braking will have a great impact, so it is not recommended in the high voltage full-speed operation of these two functions, the need to speed throttle down to 50% or below can be forced to operate the power tubes and chips may be damaged!
