HiLetgo RAMPS 1.4 Control Panel 3D Printer Control Board Reprap Control Board for Arduino Mega 2560

Had a very minor manufacturing defect with the first board I received, but the problem was quickly resolved and got a replacement board. The board has been working great, absolutely no problems replacing faulty old 3d printer board. Would highly recommend it. HiLetgo customer service was very proactive in offering assistance and was very responsive.

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.

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

Product arrived appearing crushed, and is only packaged in an ESD bag. I had to bend the yellow bits up and off of the PSU connection on the board. No harm seems done however, as it is successfully running Marlin firmware with a new Arduino mega. Comes with a full complement of jumpers.Just recieved my second board from HiLetGo. The original is still working really well. The new board seems to be working just fine on an Arduino Mega Clone. My only complaint is the solder points under the main power input on both boards needed to be filed down a significant amount to allow for installation on the Arduino Mega.6/7/2019The second board I received died yesterday.

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

My power connector also has burnt and I would not buy another from this manufacturer. It is also a crowded design and I would recommend a newer controller board for expansion capabilities

Aside from the late delivery, promised on Sunday and arriving at 9:15 PM on Tuesday, there were some problems with the fit of the board .When mating with the 2560 there was an interference between one of the four solder lugs on the main power connector of the RAMPS board and the DC power jack of the 2560 (original Arduino brand, not a clone). The interference prevented the RAMPS pins at one end from fully seating in the 2560. I used flush cutters to trim the offending lug but it wasn't enough. I finally resorted to de-soldering and removing the unused power jack from the 2560. That was better but there's still an interference between the bottom of the RAMPS board and the top of the USB jack of the 2560 and the pins between the two boards still don't fully seat at one corner. It all works but the RAMPS board is supposed to be made to fit the Arduino 2560. This one is marginal. Interference between the boards preventing full engagement of the pins is not fatal, but isn't optimal either.EDIT - After about three months service terminal block with connections from power supply failed. I dislike the 2-piece style of terminal block:b even more now. Image with two boards shows both styles. One-piece type, as on the old original board,, seems superior.

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.
