The driver board can drive hard disk brushless motors, CD-ROM brushless motor and so on, the micro 3-wire or 4-wire without hall brushless motor. This device has reverse voltage protection and over current protection.
Driver voltage: DC 5V-12V
Working voltage: <1.2A
Speed adjusts: 0%-100%
Note: Brushless motor line of receiving terminal drive plate must be pressed sturdiness, poor contact will lack of phase operation. Board terminals fixed screw clearance, please use coarser line connected to the board.
How to identify four-line motor public port? Use the resistance of the multimeter * gears test these four terminals. One of the terminals and the other three terminal resistance value of the minimum and equal. So, it's COM terminal.
