  1. I have hardware at work that has a connector for a standard four-pin FTDI serial port, and found that it was possible to use the $35 BlueSmirf module from Sparkfun. I wondered if I could find a similar module for my task at a lower price, so I ordered three different modules to test. This one was the first one I tried, and it worked perfect once I set the baud rate to match our hardware.Hookup:Four pins – TX, RC, GND and Power (3.3v – 6v).The module defaults to…

  2. I’m using this for bench-testing some firmware, so at the moment I haven’t tested the stepper drivers. But so far it’s looking pretty good for the price.The Longruner 3d Printer Controller Kit Mega 2560 R3 is working fine, and what I have tested on the Ramps board looks good as well.I did have a few minor issues getting it running- in order to use the graphic display, you need three things:1) Uncomment “”#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER”” in your…

  3. very good item but don’t hesitate to contact the seller if you don’t manage to make work the screen . They are a good help.It works okay. I bought it as spare parts for my current 3D Printer Controller Kit . Everything worked. I may use it if I make another printer.The Headers were not straight, but I was able to get it all put together without much of a struggle.The Encoder is Backwards from the normal (Inverted). This can be corrected in Marlin by updating the pins.h…
