The SparkFun Variable Load Kit is a quick-to-assemble board designed to allow users to draw a specific amount of current from a voltage input. This kit can be used to test stability of a power supply under various loads, battery lifetime, safety cutoffs and other design elements. The Variable Load Kit can test supplies of up to 30V at currents ranging from a few mA all the way up to 4A.
For safety, please be sure that the total load power is limited to 15W because, even at that wattage, the heatsink will get hot to the touch.
The variable load can be controlled using the onboard capacitive touch buttons or programmatically over UART. An optional 16×2 character LCD can be added to view the set current limit, the measured current, and measured voltage.
