DIN Rail Mount Pinout Breakout Terminal Block Module for Arduino MEGA-2560 R3 / Due

Great to have at the ready for my fiance who is a wizard at electronics and master of the CNC. He was absolutely thrilled to add this DIN rail-mount component to his Arduino kit.

This is a sturdy well built din rail mount for an Arduino Mega 2560.The din mount is very beefy, it is unlikely it would ever break under normal circumstances. The internal header board appears to be well made. The header pins lined up with my Mega 2560 board with no issues. The side screw terminals are tight against the headers, so it is a tight fit. Once the Mega is installed, you need to take care uninstalling it, as the connections are very tight and it takes a bit of force to remove the board. I found gentle by firm even pressure worked well to pull the Mega board off the din mount. It is essential to lift all the edges of the board off at the same time, so as not to bend any pins. The good news is, once installed , there is little reason to remove the Mega.Speaking of "pins" the din adapter does not have connections for the ICSP header near the reset button on the Mega. These six pins provide access to the "In Circuit Serial Programming" interface of the Mega. This interface is typically not used, as programs are normally loaded on the Mega via the USB port. However, there are some rare occasions where access to this header is required.The adapter has a reset button and green power LED on one end of the board, the other three sides are dominated by a full set of screw terminals. A 2mm flathead screwdriver fits the terminal screws perfectly. The adapter board sits a few millimeters below the plastic side rails of the din mount, as such, the bottom of the screw terminals are slightly recessed below the side rails. If you are using bare ended wire this is not an issue, however, bread board cables with plastic sheaths at the ends might be a bit of a problem if the wire does not extend far enough out from the plastic sheath. This shouldn't be too much of a concern, as it is unlikely in a production environment you would use bread board cables for the final connections.Bottom line: This mount allows for a professional installation of an Arduino Mega in a din rail environment. The mount is very sturdy and the adapter board is well made with quality screw terminals that grip wires tightly. This din mount is not inexpensive, but you get what you pay for, a robust well made mount that costs about as much as the Arduino Mega 2560 microprocessor board.

This board works very well for figuring out projects when you are going to be adding and removing sensors or controls until you get your project working the way you want.Great addition to anyone's Arduino kit box.

It never dawned on me how convenient it would be to be able to mount an Arduino Mega via din rail.I build little CNC Machines, and everything else is Din mounted. power supplies, contactors, transformers, Dinkle connections, breakers, etc....This was a welcome addition to my little eco-system, as it eliminated the need to 3D print a little mount for the board.The absolute best part is the screw terminal I/O interface. I guess I was always too cheap to buy an add-on card that cost more than the actual Arduino, but now I've seen the light! 99% of problems I've ever had had to do with busy connection clusters. This just simplified my life!The connections are secure, and I can easily test, swap something out, or make changes without either de-soldering wires, or worse yet, worrying about accidentally knocking those lousy push on pin connectors loose, causing a secondary problem. No more hot glue for me!This is a solid solution for making a Mega a permanent part of a device, which makes the overall unit look much more professional to boot.Like I said, I didn't know how badly I needed this in My life, but now that I've tried it, as someone who consumes Arduino Megas in bulk, I'll never go back!I absolutely recommend this for anyone who needs a more permanent mounting solution, but can benefit from the flexibility and uniformity of a Din rail mounting system.Two Thumbs up!

I got this to check it out for a number of potential projects, from telescope projects to a MEGA-based GRBL CNC controller. I only have a MEGA 2560 and a MEGA 2560 APK (which is no longer made) so I haven't tested this with a Due.The MEGA installs face down, which blocks access to the ICSP and reset button, but a reset button has been added to the breakout board and the ICSP can be remoted by adding a single connector to the board. (NOTE: If using a MEGA 2560 APK, which hasn't been made for a long while now, the second USB port does block the reset and ICSP. As long as you don't install an ICSP connector, everything still fits though.)There are mounting holes matching the MEGA so that it can be solidly mounted to the breakout board. Only the two in the middle are really usable as the other four around the outside are too close to the screw terminal blocks- but the two in the middle are more than sufficient to make sure everything stays in place in a high vibration environment.The USB connector and power connector are easily accessible. All pins are routed to the screw terminal blocks, so the Arduino can be powered that way as well.I really have zero complaints. Excellent board.EDIT: I'm uploading a new photo showing that ferrules when used with this board press against the DIN holder. They still work fine, but there is contact. Not a con for me but just something to know. Bare wire has no issues.

I can't say it enough how much I appreciate DIN rail-mounted components. They elevate the organization and aesthetics of projects and panels. This DIN Rail Mount Breakout Module designed takes it up a notch. The quality is exceptional — from the robust bracket to the clear labeling and well-crafted PCB. It's not just functional; it's a durable and reliable solution. While I'm not a huge fan of the green color (I prefer gray or black), it seems to be the norm for these mounts. It's a solid five stars from me. I hope this helps to make a decision.
