This version is item #5340 with soldered header pins, so no soldering is required to use it with an appropriate 16-pin socket or solderless breadboard. It has an adjustable current limit that can be set with an on-board potentiometer and a four-layer PCB for better thermal performance, allowing it to deliver up to approximately 1.2 A continuous per phase without a heat sink or forced air flow (2 A peak).
