ELEC-0128 Sir Ramps-a-lot is a handy PCB that makes it easy to connect a small scale 3D printer driver like a RAMPS or RUMBA board to a larger driver than the normal A4988 & co.
ELEC-0134 Dark Knight is the nega-verse edition: some larger drivers want signals that are reversed. This board adds transistors to do just that!
We use three of each on the Sixi Robot to keep our wiring nice and tidy.
This order comes with three (3) transistors and male/male 0.1 pitch headers.
Some soldering required.
