【求教】关于28BYJ-48的问题

例程如下，应该不会出现速度过快的情况
// Adafruit Motor shield library
// copyright Adafruit Industries LLC, 2009
// this code is public domain, enjoy!
#include <AFMotor.h>
// Connect a stepper motor with 48 steps per revolution (7.5 degree)
// to motor port #2 (M3 and M4)
AF_Stepper motor(48, 2);
void setup() {
Serial.begin(9600); // set up Serial library at 9600 bps
Serial.println("Stepper test!");
motor.setSpeed(10); // 10 rpm
}
void loop() {
Serial.println("Single coil steps");
motor.step(100, FORWARD, SINGLE);
motor.step(100, BACKWARD, SINGLE);
Serial.println("Double coil steps");
motor.step(100, FORWARD, DOUBLE);
motor.step(100, BACKWARD, DOUBLE);
Serial.println("Interleave coil steps");
motor.step(100, FORWARD, INTERLEAVE);
motor.step(100, BACKWARD, INTERLEAVE);
Serial.println("Micrsostep steps");
motor.step(100, FORWARD, MICROSTEP);
motor.step(100, BACKWARD, MICROSTEP);
}

谁能告诉我这个步进电机和驱动板该怎么接线啊？蓝粉红橙黄分别对应那几个孔？红色到底是接地还是接5v？

// to motor port #2 (M3 and M4)(M=Motor)
你接的是(port #1 M1 and M2)

这个是关于这个板的所有资料

这种步进电机如何连接齿轮
