How to install a shield?

OpenMV Boards

This might seem like an obvious question, but I couldn’t find an answer anywhere - how do you install a shield?

I have an OpenMV H7 Plus and a Wifi shield - the best I was able to do was put it underneath the OpenMV and then use the included posts to hold it in place from the top, but then the wire legs are just dangling underneath. Is that how you’re supposed to do it?

Is there a diagram or picture somewhere showing how to install it?

Thanks!

Shields are stacked with the long headers, see the product page WiFi Shield | OpenMV

Oh, I see like this - https://cdn.shopify.com/s/files/1/0803/9211/products/web-new-wifi-cam-quarter_f980583f-5468-42a0-9072-cc67947f2662_grande.jpg?v=1577303380

I had assumed it would plug in solidly. :open_mouth: Is there any kind of system that lets you do it without soldering?

Next gen, right now it’s soldering.

Thank you guys :slight_smile: Eventually got it soldered on there. I really like this camera!

@bburnskm You could solder female headers to the camera and then solder male headers to the shield. Then you can remove the shield at your convenience.

Depending on the shield you can also orient the headers front or back if the shield allows it for space.

That is how I attach the shield I designed. This way if it were to fail in prototyping or I need the camera for something else it is possible to disassemble.

Hi,

I installed the wifi shild and soldered it with OpenMV Cam H7 plus.
I configured the setting file to connect on start up.
when I run connect.py or scan.py I get this error
OSError: Failed to initialize WINC1500 module: Init failed!
at line
wlan = network.WINC()

I can’t attach photo of how I stack them because I’m a new user.

Hi, it should be connected with the removable headers…

Yup, that seems correct.

So what is causing the error ?

You only need to do this if you want to use the WiFi shield to program the cam. If you configure the settings file you can Not use the WiFi shield scripts like you do. To remove the config file just erase the flash from the Tools menu.
