I'm using,

• GoPlus controlled with M5Stack Fire
• 130RA motors( https://akizukidenshi.com/download/ds/mercurymotor/FA-130RA-2270_20190306.pdf )
• External stabilized power supply 5.5V

My Investigation are following.

I uploaded this simple code to my GoPlus module.

//GoPlus Motor Debug code for Atmega328
const int IN_0 = 9;
const int IN_1 = 10;
const int IN_2 = 11;
const int IN_3 = 3;

void setup() {
  pinMode(IN_0, OUTPUT);
  pinMode(IN_1, OUTPUT);
  pinMode(IN_2, OUTPUT);
  pinMode(IN_3, OUTPUT);
}

void loop() {
  digitalWrite(IN_0, LOW);
  digitalWrite(IN_1, LOW);
  digitalWrite(IN_2, LOW);
  digitalWrite(IN_3, LOW);
  delay(2000);
  digitalWrite(IN_0, HIGH);  //M0  ---NG--------
  digitalWrite(IN_1, LOW);
  digitalWrite(IN_2, HIGH);  //M2  --OK: but rotates Intermittently--
  digitalWrite(IN_3, LOW);
  delay(2000);

  digitalWrite(IN_0, HIGH);
  digitalWrite(IN_1, HIGH);
  digitalWrite(IN_2, HIGH);
  digitalWrite(IN_3, HIGH);
  delay(2000);
  digitalWrite(IN_0, LOW);   //M0  --OK: but rotates Intermittently--
  digitalWrite(IN_1, HIGH);
  digitalWrite(IN_2, LOW);   //M2  --NG--------
  digitalWrite(IN_3, HIGH);
  delay(2000);

  digitalWrite(IN_0, LOW);
  digitalWrite(IN_1, LOW);
  digitalWrite(IN_2, LOW);
  digitalWrite(IN_3, LOW);
  delay(2000);
  digitalWrite(IN_0, LOW);   //M0  --OK: rotates Continuously--
  digitalWrite(IN_1, HIGH);
  digitalWrite(IN_2, HIGH);  //M2  --OK: rotates Continuously--
  digitalWrite(IN_3, LOW);
  delay(2000);

}

Only following case works well, but others don't...

  digitalWrite(IN_0, LOW);   //M0  --OK--
  digitalWrite(IN_1, HIGH);
  digitalWrite(IN_2, HIGH);  //M2  --OK--
  digitalWrite(IN_3, LOW);

• The voltage(HIGH / LOW) of IN_0 to IN_3 of LV8548 are correct for all cases.
• I replaced to another GoPlus module, but it was exactly the same.

To drive 130RA motor, GoPlus is too weak??
