This is a dummy load. This device developed to test your power sources, battery, supply circuit, power bank etc. You can set constant current level with built-in potentiometer or analog input voltage. You can read actual current value with multimeter or Arduino like development board. Only read analog voltage and convert to current with our examples on github.

You can directly access Arduino examples on SLB github page. No wait to test!
