J-SMU | DIY source-measure unit

J-SMU is a HTML library typically used in Internet of Things (IoT), Arduino applications. J-SMU has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

In case you don't know what is SMU, take a look here Basically, it's glorified power supply, able to both source voltage (and measure current, with current limit) or source current (and measure voltage, with voltage limit), usually in wide range of voltages and currents. It usually works in four quadrants, meaning it's able to both sink and source power. When set to zero output voltage, SMU acts as ammeter and when set to zero current, acts as voltmeter. It's very useful as general purpose PSU with precise setpoint adjustment, as a tool for measuring high resistances, for testing semiconductors in wide range of voltages or currents. You can do all this things using classic lab tools (PSU, ammeter, voltmeter, switches), SMU offers this all in single package and is designed to be interconnected with computer to automate the tasks.
