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.
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).
This little 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.

TB6612FNG電機驅動器可以在1.2A(3.2A峰值)的恆定電流下控制兩個直流電機。兩個輸入信號(IN1和IN2)可用於控制電機的四種功能模式之一:順時針,逆時針,短制動和停止。兩個電機輸出(A和B)可以單獨控制,每個電機的速度通過PWM輸入信號控制,頻率高達100kHz。 STBY引腳應拉高以使電機脫離待機模式。
邏輯電源電壓(VCC)可以在2.7-5.5VDC範圍內,而電動機電源(VM)限制在最大電壓15VDC。輸出電流的額定值高達每個通道1.2A(或短的單脈衝高達3.2A)。
如圖所示,這個小電路板安裝了所有組件。兩個電源線都包含去耦電容。 TB6612FNG的所有引腳分成兩個0.1英寸間距的接頭;這些引腳排列成輸入引腳在一側,輸出引腳在另一側。
