Great! Thanks for the answer, I did thought about  repairing the board, but decided to stick to a plug and play solution this time.

You should also consider just buying a proper board instead of another outdated RAMPS. The price difference is almost negligible these days.

# Replacing RAMPS 1.4 for 1.6

(Asked by: username_0 on 2019-08-21)

During the assembly of my printer, I accidentally shorted the RAMPS 1.4 board, looking for a replacement I found the RAMPS 1.6 which would eliminate the need for a MOSFET power module.

My question is, could I simply replace the RAMPS 1.4 for the 1.6 or should I make any other modification?

RAMPS 1.6 is very similar to RAMPS 1.4. Most, if not all, of the changes are hardware improvements, without making the core functionality different. Looking at the incremental changes between versions:

So, in short, yes, the RAMPS 1.6 *should* be a direct plug in replacement for the RAMPS 1.4.

That said, you *may* be able to salvage your RAMPS 1.4, if you can locate the part that has given up the "magic smoke". It could just be a blown capacitor, or diode. There have been [a number of questions](https://3dprinting.stackexchange.com/search?q=RAMPS) relating to that, so it might be worth searching for answers here, on SE.3DP1.
