Open Source Programmable DC Electronic Load

January 2023

A testing device that is meant to verify the operation of power supplies and batteries for long periods of time. Designed to be affordable and accessible to makers and hobbyists for future improvements. Plugs directly into a laptop or PC via USB-C and allows the user to control it via serial commands. Tracks the temperature of the Device Under Test (DUT), internal temperature, current drawn, load voltage, and total power consumption. Controls its own fans to cool the PCB and the load resistors. Allows the user to set constant current, constant voltage, and constant power modes for a variety of testing procedures.
