Shield V1 Capacitor Pop

by merreko on Tue Nov 30, 2021 7:33 am

Hi,

I was attempting to make a NEMA 17 motor to move the magnet fidget spinner I made and the capacitors pop, would someone know why?

Power:
15V / 5A

Nema 17:
RoHS
p/n 17HS 13 - 0404S1
s/n 202005290093

Shield:
Adafruit V1

Arduino:
elegoo uno r3

Code: Select all | TOGGLE FULL SIZE
#include <AFMotor.h>

AF_Stepper Stepper1(200, 1);  // A 200-step-per-revolution motor on channels 1

int rot = 10;
int sp = 600;

void setup() {
 Serial.begin(9600);
  Stepper1.setSpeed(sp);

}

void loop() {
 
   Stepper1.step(rot, FORWARD, INTERLEAVE); 
}

That is not an Adafruit board. Many of the clone manufacturers copy our designs but substitute lower cost parts. And electrolytic capacitors do degrade over time as the electrolyte dries out.

Also,
by using all yellow wires on the terminal strips,
was the motor voltage applied with reversed polarity?

Good point. The polarity as shown in the photo is correct because the power LED is on. But reverse polarity is one good way to destroy to an electrolytic cap.
