      Very pleased with the quality and price

      compact, all-in-1 Ramps 1.4 board/ arduino combo . Very convenient design, the motor connections are simple and more organized than a traditional Ramps board. Very pleased with the quality and price.

      Saves space and works great

      Really cool. I use it to run a custom made Delta printer. I find it overheats less than the arduino and shiel package. It's easy to find the wording guide online not that you will need it. Very intuitive.

      Excellent upgrade to my 3d printer

      I decided to go with this board to replace my old Melzi controller due to it the limited flash memory. This has worked flawlessly, I had no issues with finding the documentation I needed online to wire up this board. It booted right up the first power on and flashed the firmware with no issues. I took the suggestion from the previous review and used some ferrule crimps for the wire ends to the screw terminals. I would also pick up some 2.54mm dupont pins/headers as I had to crimp that on for the endstop connections to make a clean install. Compared to my old board this board runs very smooth. I coupled it with some A4988 drivers and my printer runs even quieter than before. The hotbed chip does get pretty hot when the bed is heating up to temperature, but cools down once it hit the maintain temps. I would recommend adding a heat sink to all the driving chips on this board for additional cooling, but the board seems to run cool overall so far.

      At first glance looks good.

      Auto loads drivers for usb connection but need some documentation re pin outs for programming firmware.

      Very nice board. Just a couple things to note

      Very nice board. Just a couple things to note. It's obviously not the same size as an Arduino Mega 2560 with a RAMPS 1.4 hat, so if you're ordering one to replace one of those, keep in mind that the holes aren't going to match. I'm going to print out some sort of bracket that will allow to me put it where my old setup was, but for now it's sitting on my desk under my printer. Also, make sure you read this from beginning to end as it has a lot of great information:
