About the Smu switch PCB

Smu switch is an open source PCB design by jaromir-sukuba, published on GitHub. It is a 2-layer board measuring 38 × 113 mm, with 4 components from 3 distinct parts.

By type, the board carries 2 connectors, 1 fuse and 1 switch.

From the project

DIY source-measure unit

Parameters: + Voltage ranges 12V and 120V (bipolar) + Current ranges 1uA, 10uA, 100uA, 1mA, 10mA, 100mA (bipolar) + Minimal set voltage step - 1mV + Minimal set current step - 100pA + Voltage resolution - 100uV + Current resolution - 1pA

JSMU is designed to work as standalone device, but can be connected to computer via USB, and controlled via simple commands in SCPI form, similar to Keithley 2xxx series SMUs.
