Summary
Ever wanted to run your RepRap from SD card? Here is your chance! This RAMPS add-on enables you to print from MicroSD.With RAMPS 1.3 and higher it's easily connected to the RAMPS board. You will require special firmware though.
Where to get it?
Depending on the vendor you can buy SD Ramps as bare PCB, DIY-kit or preassembled.

Component soldering
The following steps will show you how to solder the board. These components are Surface mounted, so this can be a but tricky. You will need a soldering iron with a small tip. Other than that, it is doable if you have a bit of experience.
Step 1 Examine the PCB. Try to figure out what goes where. |
|
Step 2 Place the 74HC4050 on the PCB. Some chips do not have clearly marked how they should be put on the board, just place them with text on the chip aligned to the north side of the PCB. Solder one pin (if you are right handed, working from left to right is a good order) and align the other pins to the pad. Solder a second one, check the alignment and then the other pins. |
|
Step 3 Next is the MIC5209-3.3YS. Place it on the pads and solder the pins. Can't go wrong here. |
|
Step 4 Turn the pcb and put the capacitor on the pads,mind the white band! I like to put solder on one pad first, put the capacitor on and melt the solder again. Then solder the other pad. |
|
Step 5 The SD socket is probably the hardest part. Your socket should have eight or nine pins. Place the most left pin on the most left pad. If you have eight pins, a pad on the right remains unused. |
|
Step 6 Next put the resistor and LED onto the board. The resistor can be put on either way, the LED can only be placed with the +-polarity on the left. |
|
Step 7 Finally put on the headers and you are good to go! |
