说明：  MS41929 是一款双通道 5V低压步进电机驱动芯片，通 过具有电流细分的电压驱动方式以及扭矩纹波修正技术，实 现了超低噪声微步进驱动。 芯片另外内置一个直流电机驱动器，上下开关的电阻之 和低至 1.1欧姆。 MS41929内置了晶振放大模块，可以使用无源晶振。
(Ms41929 is a dual channel 5V low voltage stepping motor driver chip Over current subdivision of voltage drive mode and torque ripple correction technology, real Now the ultra-low noise micro step drive is realized. In addition, a DC motor driver is built in the chip, and the resistance of the up and down switches is And as low as 1.1 ohms. Ms41929 has built-in crystal amplification module, which can use passive crystal oscillator.)
