RepRap Mega Pololu Shield, or RAMPS for short. It is designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduino Mega with the powerful Arduino MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Arduino MEGA shield for easy service, part replacement, upgrade-ability and expansion. Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack.
Features：
1.It has Cartesian robots and regulations of the extruder .
2.Extended to control other accessories.
3.Heater / MOSFET outputs and three fan thermistor circuit.
4.Integration of additional security 5A and component protection.
5.Control of additional heating bed 11A fuse.
6.Suitable for 5 Pololu stepper driver board.
7.Pololu board pin socket, so they can be easily replaced or removed for future designs.
8.I2C and SPI pins left for future expansion.
9.Hooked into all MOSFET PWM pin versatility.
10.Servo type connector is used to connect to the end stop , the motor and the light-emitting diodes. These connectors are gold-plated , rated current of 3A, very compact.
11.On the SD card to add - is now available from the Kliment - Sdramps.
12.LED indicate when the heater output.
13.Option 2 motors connected to Z Prusa Mendel.
Package Included：
1* RAMPS 1.4 Control Panel 3D Printer Control Board Reprap Control Board

OK, it is a basic RAMPS board but the connections seem to be the issue. I replaced an older board with this one and one hour into the run, the bed control overheated and locked on. After an overheat shutdown, I pulled the board and found the power transistor and bed connection to have overheated and melted as seen in the picture. It seems the failure melted the power strip which will happen with this type of strip. This was a direct replacement for an old board which had a cracked power connector so I tried this on, I'm back to the old one now.

worked fine for a while then something started smoking a ruined everything. not sure what failed but parts on this are cheap. still it worked for a while and it isn't expensive. ordered replacement for failed unit so hope it does ok.

I do wish these came with heat sinks on the MOSFETs, but that applies to everyone's RAMPS board.

If you have an Arduino/clone MEGA2560 lying around, for just ten measly dollars, you can slap 5 TMC2209s in here [~$30 or less] and have a pretty damn good klipperized motion control system with full UART configuration [TMC modification required as this board doesn't come with plug and play provisions for 2209 UART].Only negative is that because the Arduino is 8 bit, you can't really do more than 16 microsteps [the TMCs can interpolate up to 256 but you lose a little accuracy, whether or not you care is a different story] frankly its not a big deal, and isn't a failing of the board, and anyway if you really wanted to go full 32 bit/256 microsteps there are plug and play MEGA style boards with 32 bit micros out there, not the easiest to find but its a definite option - Though at that point you might be better off monetarily by getting a board with everything already on board, there are arguments for both options. I can't speak to any possible bed heater power issues as i'm using my 3d printer's stock board to control that and am using this to control a 70W hotend cartridge heater off of the bed heater output. For my purposes this is pretty much perfect.

Bought this board as a spare since I had a mega that wasn't being used. Works good.

Blew 5 volt regulator..Was able to repair. Seems to be an issue with the mega. Happens with other manufacturers. Otherwise , it works well.*UPDATE: Customer service was great. They went above and beyond to ensure that things were made right. Great example of a company that values it's patrons. Thank you. *

Couple of the pin headers underneath had some "woodish" debris sticking out. Plucked it out, simply. This is the 2nd one I've gotten from these guys. Picked up the second because these RAMPS are cheap and I needed to troubleshoot a TMC2130 upgrade gone awry. The 1st had pins soldered to the 12V AUX, not on the 2nd. 1st had orange LEDs, 2nd has red. Both still work. If I EVER need another, due to some other mod or upgrade gone awry, because of my infantile, prepubecent electronics knowledge I will surely get it from these guys. Their chinesium is of the highest quality.

Used this as driver shield for an Arduino MEGA on a 3D Printer. Other than having a loose screw pin on the power output port used for the heatbed, everything else worked wonders. Despite accidentally reversing polarities of some connections and smelling a burnt scent on two occasions, this board is still up and running, forgiving!
