The TB6612FNG Motor Driver can control up to two DC motors at a constant current of 1.2A (3.2A peak). Two input signals (IN1 and IN2) can be used to control the motor in one of four function modes: CW, CCW, short-brake, and stop. The two motor outputs (A and B) can be separately controlled, and the speed of each motor is controlled via a PWM input signal with a frequency up to 100kHz. The STBY pin should be pulled high to take the motor out of standby mode. Due to popular demand, this version of the SparkFun Motor Driver includes pre-soldered male headers for ease of use. With the headers already soldered on, you can jump right in to using this little board without any assembly!
Logic supply voltage (VCC) can be in the range of 2.7–5.5VDC, while the motor supply (VM) is limited to a maximum voltage of 15VDC. The output current is rated up to 1.2A per channel (or up to 3.2A for a short, single pulse).
The board comes with all components installed as shown. Decoupling capacitors are included on both supply lines. All pins of the TB6612FNG are broken out to two 0.1" pitch headers; the pins are arranged such that input pins are on one side and output pins are on the other.

該TB6612FNG電機驅動器可以在1.2A(3.2A峰值)的恆定電流控制兩個直流電機。兩個輸入信號(IN1和IN2)可以被用於控制在四個功能模式之一的馬達:CW,CCW,短制動,並停止。兩個電動機輸出(A和B)可以單獨控制的,並且每個馬達的速度通過PWM輸入信號的控制用頻率高達100kHz。在STBY引腳應拉高到乘坐動退出待機模式。由於大眾需求,這個版本的SparkFun電機驅動器包括易於使用的預焊男頭。隨著頭已經焊上,你可以使用這個小板上沒有任何集會跳吧!
邏輯電源電壓(VCC)可以在2.7-5.5VDC的範圍內,而電動機供給(VM)被限制為15VDC的最大電壓。輸出電流額定功率高達1.2A每通道(或最多3.2A很短,單個脈衝)。
該板安裝如圖所示的所有組件。去耦電容都包含在補給線。所述TB6612FNG的所有引腳都細分兩個0.1“間距頭;銷被佈置成使得輸入引腳在一側和輸出管腳都在其他。
