Adafruit Stepper Motor HAT - Raspberry Pi

Post by hhk »

High,

I lately purchased the dc stepper Motor hat.
Now I got two questions:

I would like to use the stepper hat on a bread board and not as a hat.
Which GPIO Pins do i have to connect at least to get the board running

Is there any possibility to breakout of the raspberry and still use the hat and the GPIO Pins?

Thanks in advance
greetings Helmut

You need connections to GND, 3.3v, SDA and SCL. If you build the Hat with stacking headers, you will have access to all the GPIO pins via the stacking header.

Sorry again,

it did not do the trick.
I connected pin 1, 3, 5 and 9, your sample programms fail.

Do I have to connect all ground and 3.3V ?

Any idea
greetings
Helmut

According to the schematic, all of the 3.3v and GND pins are tied together. If you post photos showing all your soldering and connections to the board we can take a look.

Can you post a larger image that clearly shows the soldering?
