I think it is important that I talk a little about component placement.
As it stands I have gone through several iterations for my exiting KRMx02 components.
Shown here is one roughly based on my DIN Rail Madness write-up.
The difference is I have mounted a PC, power supply, and VFD controller to the board. Not much room for the 5 components and 5 terminal blocks I need to add for this upgrade.
Had I not added the VFD and PC, I would probably have the room to add the upgrade components. What I am trying to get at is that many of you will have already made changes to your layout. There is no way I can accommodate them all so I will show you what I did to upgrade my current layout.
I decided to mount an adapter board to my power supply using the four M3 mounting holes.
The adapter is made from 1/4” pegboard, and will be used to attach a large piece via a set of hinges.
Here I attached the main layout board to the adapter board using 3 hinges and 6, #6-32 x 1/2” machine screws and nuts.
These are the hinges I used:
I added a piece of #10-24 threaded rod to allow airflow under the board.
I can now freely swing the upgrade board up and out of the way if I need to access the components below the board.
Conclusion
A few things before moving on.
Mounting Components
The majority of the components are mounted using #6-32 x 1/2” machine screws as shown here.
To mount both the breakout board and the UC300ETH, I mark and drill four holes and insert #6-32 x 3/4” machines from the bottom. I secure them with nuts as shown.
I keep the nuts loose to make it easy to align the two boards to the screws.
Once the board slips over the screws, you can tighten the screws from the bottom. In most cases the board is held in tight enough that you dont need nuts on the top of the board.
My Layout
This is how I decided to layout my components for this upgrade.
The two terminal blocks in the upper right corner are the GND and 48V blocks.
The two terminal blocks in the lower right corner are the GND and 12V blocks
The terminal block in the lower middle is the 5V block.
As a final note on the UC300ETH placement, it is important to place the UC300ETH close enough for your cable to reach.
Make sure you test all positions if you are mounting your components on a hinged layout board.
