双路电机驱动原理图及PCB布线图，两个电机单独控制，可以实现电机的正反转，电机的PWM速度控制。(Dual motor drive schematic diagram and PCB wiring diagram, two motors separately control, can achieve positive and reverse motor, motor speed control of PWM.)

使用逻辑分析仪抓取的一定位对一脉冲或两定位对一脉冲两种EC11旋转编码器的时序图。包括正转，反转，连续正转，连续反转时序。(Timing diagrams of two EC11 rotary encoders captured by logic analyzer for certain bits to one pulse or two to one pulse. It includes forward rotation, reverse rotation, continuous forward

很多场合需要增加电源反接保护，该文档列出针对小功率的反接保护，成本低廉(Many occasions need to increase the power reverse connection protection. The document lists the low power reverse connection protection, and the cost is low.)
