This board is a drop-in replacement for the A4988 Pololu board. It is superior in that it can handle 1.5A instead of 1A without extra cooling, and rated upto 2.2A with a heatsink and fan. It also has microstepping resolutions down to 1/32 microsteps (instead of 1/16th)
Comes with a header strip which needs to be soldered on for mounting to a RAMPS shield, but is left off so you have the option of using it in a different way, such as attaching to a ribbon cable or breadboard.
Supplied without a heatsink (available seperately).
