• touchscreen / rotary encoder / button pad as physical interfaces
• can be battery powered or from, for example, a computer power supply
• cach output is isolated

Some features that are also considered for this device:

• Ethernet and GPIB control
• dedicated control and measuring program for PC
• Raspberry PI based display interface

Some of the in this repository included files are:

• KiCad files (.kicad_pcb / .sch / .pro / .lib / bom / footprints etc.)
• Schematic (pdf)
• Gerber files
• stability, ripple measurements
• calibration data and excel sheet

This device and all of its included branches are currently in the first engineering / prototyping phase.
