Based on official datasheets for the L293D chipset and the HW-130 module , the technical limits are as follows: 4.5V to 25V (typical) or up to 36V . hw 130 motor control shield for arduino datasheet
This happens when motors draw too much current from the Arduino's 5V rail. Always use external power for the shield. | Parameter | Value / Range | | :--- | :--- | | | 4
void setup() pinMode(IN1, OUTPUT); pinMode(IN2, OUTPUT); pinMode(ENA, OUTPUT); Always use external power for the shield
