Plastic container for two PCBA

[Alessandro Locati]

Hello,

please I have to build a container for these two PCBA:

https://www.nordicsemi.com/Products/Development-hardware/nrf9160-dk

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_nrf7002.html

these two PCBA must to be stored in the same craddle with the access to the USB connectors.

Please, do you have something already customized for this issue?  Plastic container, plastic craddle, etc.

thank you very much

best regards

Alessandro

Hi Alessandro,

We don't sell any enclosures for our development kits, and as far as I know we don't have any CAD models for them either. Do you have access to a 3D printer?

I tried searching Thingiverse for 3D-printable designs. For the nRF9160-DK I could only find this base. For the nRF7002-PDK, I found this fully enclosed NRF52840-DK case, which should fit.

The 52840-DK, 52833-DK, 5340-DK, and 7002-PDK share the same exterior dimensions, the same placement of the debugger USB port, and the same hole placement for PCB stand-offs. The 9160-DK shares the same, except that it is about 10mm longer and loses the stand-off hole near the antenna. So, you could simply extend your design to accommodate the 9160.

You might also like this 3D-printable generic enclosure.

If you need ingress protection or don't have a 3D-printer, I recommend just buying a generic plastic sealable container, and adding either USB passthrough connectors, or cable grommets (waterproof if necessary).

Hope this helps!

Best regards,

Raoul

Hello Raoul,

thank you very much for your answer. We will build a box in 3D printing to place the two PCBA. Please, to model correctly the parts of the PCBA-Box we would like to have the 2D drawing or the 3D model of the two PCBA, are these documents available? The boards that we need are these:

Thank you and best regards,

Hi Alessandro,

2185.step

Here is the step file for the nRF9160-DK.

I also discovered that my colleague had already designed an enclosure for the nRF9160-DK. I encouraged him to share it: https://www.thingiverse.com/thing:5671338

If you design your enclosure for the nRF9160-DK, you can expect it to fit the nRF7002-DK will fit as will. The pins and standoff-holes all follow the format of the Arduino Uno.

The nRF7002 is mostly identical to our nRF52840-DK. Only the lower right corner is shaped differently, to accommodate the antenna design:

By the way - almost all of our hardware files are actually available for download. Among the nRF9160-DK files you will find 400389.PcbDoc which can be open in Altium Designer. From there, you can export the file as for example .step.

If no one on your team has Altium, you can try opening it in the Altium online viewer, which I believe has an export function if you create a free account.

You could also try opening the file in KiCad, and exporting the 3D model from there.

For the nRF7002, unfortunately there are no downloadable hardware files available yet, as it is still in limited preview.

Hope this helps!

Best regards,

Raoul
