The SD6128 features a heat pad on top of the chip making heatsink easier and more efficient. It does not rely on the already small PCB area to dissipate heat. Comes with heatsinks that cover the entire chip. No soldering required as all pin headers comes pre-soldered.
See user guide before attempting to install. Do not operate without heat sink.
This driver takes manual Vref adjustments and is for use with boards without digital pot controller available. RAMPS, RADDS, and most third party controllers. The Azteeg controllers can use these drivers as well but will work with the digipot version if needed.
