This post describes a metal enclosure suitable for use with the RIoTboard provided you have some time and access to the proper tools.

 

I have been looking for an enclosure for my RIoTboard for a number of reasons:

 

1.  I have a tendency to inadvertently press the reset switch (S1) if I use the board in my workspace without any enclosure and attempt to move the board.

2.  My workspace is prone to static discharge for a number of reasons, and I would like to avoid frying the board.

3.  I have radio equipment in operation in close proximity, and I need a means to prevent RFI from the RIoTboard and any associated equipment.

4.  I would like to mount additional hardware such as a Real Time Clock (RTC), etc. for use with the RIoTboard.

 

All these factors pretty much dictate using a metal enclosure for the RIoTboard.  After some research, I settled on a CU-3005A enclosure from BUD Industries.  This enclosure is aluminum and measures 5 inches x 4 inches x 3 inches (12.7 cm x 10.16 cm x 7.62 cm).  More information is available here:

This enclosure has no pre-drilled holes or openings, so it is necessary to drill mounting holes and create openings for access to any desired ports.  I have access to a drill press and a variety of drill bits and metal files, and these were sufficient for the task.

 

Here are some photos of the RIoTboard and enclosure:

As can be seen from the photos, the enclosure is barely large enough to accommodate a RIoTboard with an SD card inserted in the J6 slot, if the board is mounted with the audio connectors (on the other side of the board) flush against the inside of the enclosure.  I have created openings only for ports I plan to use externally, but it would be a simple matter to add additional openings if needed.  I used #4 screws, lock washers and nuts to mount the RIoTboard in the bottom of the enclosure.  I also added a small opening on the end with the Ethernet and USB ports to accommodate a Serial Debug Port cable on the J18 connector (visible in the lower left of the fourth photo).

 

Nothing fancy, but it fit the bill with a total cost of less than $10.00US for the enclosure and mounting hardware.  Now I need to put my Embest LCD8000-70T in a metal enclosure as well...

It turns out that this enclosure nicely accommodates some of the available add-on boards that connect through the RIoTboard GPIO pins provided the RIoTboard is mounted as indicated above.  For example, the RIoTboard Adapter can be inserted with plenty of room for attachment of the various types of hats and expansion boards that it supports:

The LCD-EX module that is used to connect the Embest LCD8000-70T 7-inch display also fits within the enclosure:

I have cut a slot through which the ribbon cable from the LCD8000-70T can be connected to the J1 connector on the LCD-EX.
