Arduino Nano Every Board + Adafruit A4988 Stepper + Nema 17 Motor Not Getting Power

Hello,

Very new to electronics but having a good time.

I’m wondering if someone would be able to help me troubleshoot.

I have my arduino Nano Every Board connected to my breadboard along with my Adafruit A4988 stepper, Nema 17 Motor, and 100uF 35V capacitor.

Right now, I have my power supply connected to the rails on the right, then a capacitor on those rails.

From there, I have connections going from the rails, to my VIN and GND on my Arduino.

From there, I have my 5V going from my nano to the VDD pin on my 4988 stepper.

I have the GND, on the other side of the Arduino, connected to the GND on the A4988.

I have the DIR on the A4988 connected to D2 and Step on the A4988 connected to D3.

I have all 4 wires from the motor, connected to the A4988 and nothing connected to the + or - of the A4988.

When I plug in my power supply, I am not getting power to either the Arduino or the A4988.

Can anyone help me figure out what I need to do in order to get power?

maybe solder pins to the Arduino? Without this, the current will have a hard time

Ahh okay got it, thank you! Will give that a go.

You have to actually connect the power to the board for the board to get power. Without solder the pins are just sitting there in the holes. There is no connection there.

Oh okay, that makes sense! Thank you!

what i see in the image : you connect the rail (power supply) to 3.3v pin on Arduino , and then from pin 5v on Arduino you power up the 4988 stepper module. i thing you need different approach.

what is your power supply voltage?

if you have (multimeter tester) check the outlet voltage, without motor being connected.

and then lets try like this:

1- connect the supply power 5v to the rail on your board. 2- from the rail connect the Vcc & G separately for (Arduino Nano and Adafruit A4988 Stepper) (power up each board separate).

make sure you connect the right 5v from Arduino to rail (power suply 5v).

i think it will work .

first he needs to solder those pins
