USB-C breakout board for nano... help!

Community General Discussion

Hi,
I'm using a nano to power a simple circuit (led's, stepper motor, ON/OFF/ON switch). I want to mount a USB-C female plug through the wall of design so a user can plug into it with a power bank or external power source like a phone charger.
The boards i bought off Amazon are:

For some reason, if i plug lead direct to nano, everything works fine, but when i plug into the breakout board i get nothing.
I wired G to GND and V to 5V on nano. I tried soldering a male connector to the board which plugs into the nano directly and still nothing.
Cables, checked and fine.
Breakout boards though, i am looking for 5V across G and V and get no reading on my multimeter.
I've tried various cables and power supplies and get the same result - nothing through b/out board, works perfect when plugged direct to nano.

I have probably missed something stupid, but i'm scratching my head here thinking of new things to try to get it to work. Any ideas guys? What am i doing wrong?

I hope that you don't mean that literally because a Nano board of any kind is not designed to be used as a power supply beyond sensors with a small current consumption and a stepper motor usually falls outside of that definition

Please post a schematic of your project

Does the breakout board give you access to all 24 pins? If so, did you wire up BOTH 5V and both G PLUS shield to G?

i drew a circuit diagram.
Breakout board is female.
I tried soldering it to a male connector to fit directly to arduino and that doesnt work either... there's no power going through the b/out board somehow

i have no idea... there are 4 pins on the b/out board V, D-, D+, and G

Here is the disgram the right way up

How is the stepper powered ?

7

Yeah, apologies for it being upside down.
The stepper is powered from the ULN2003.
I just realised i missed 2 wires from the diagram - ULN2003 5V to 5V on arduino
ULN2003 Gnd to GND on arduino

8

So the stepper is powered by the 5V pin on the Nano

Dare I ask what the current consumption of the stepper is ?

In that case, reverse the USB-C plug in case they only connected 1/2 the pins.

Doesn't look like the soldered the power pins!

Yes 5v pin on nano to ULN. Stepper plugs to ULN.
Its only a 28byj-48. I believe it is 240mA

12

Ive tried reversing and theres nothing

13

Not my proudest soldering moment, but see what you

Those look quite different from the ones on the website. Maybe they sent you the wrong ones
Also there are no pulldown resistors so it may not work with most power sources.

Yeah, thats what i ended up with... is it much trouble to add pulldowns?

16

It looks like you may have damaged the board. If you have another board you didn't try to solder yet, just put female dupont wires on the board and solder your wires to the ends of the dupont leads.

17

Ive got 10, brand new. Ive tried several and i get nothing from any them...
I cant find a voltage across any of them. I tried plugging into a power bank which runs the nano without issue. Tried samsung usb-c charger and same thing....

18

I will have a look into those boards, thanks

19

I will see if I can find my breakouts later today and do the same test. You may have fakes.

Yes.
Which nano are you using?
