int enA = 9; int in1 = 8; int in2 = 7; void setup() pinMode(enA, OUTPUT); pinMode(in1, OUTPUT); pinMode(in2, OUTPUT);

No. Both motors share the same VMS supply. Use separate modules for different voltage requirements. gyd9e datasheet

void loop() // Forward at half speed digitalWrite(in1, HIGH); digitalWrite(in2, LOW); analogWrite(enA, 128); delay(2000); int enA = 9; int in1 = 8;

// Reverse at full speed digitalWrite(in1, LOW); digitalWrite(in2, HIGH); analogWrite(enA, 255); delay(2000); int enA = 9

No. Braking shorts the motor terminals, but energy dissipates as heat in the driver.
