This is a simple single-sided PCB design (+schematic included) for the TL071 *family operational amplifiers. I have used this IC in various projects over the years, and this board was born as a development tool / development instrument.
This KiCad project was developed and published by Francis Studios in 2025
The circuit board is designed for single sided PCB manufacturing (homemade PCB etching technologies) and was Open Sourced by the above mentioned project author. Only use at your own risk and responsibility! The repository / project owner does not take any responsibilities for injuries or broken equipment.
Operating voltages from 9VDC-16VDC but the recommended supply is 12VDC as it was the development environment and test supply level.
The IC can take even higher voltages, with changing components we can archieve higher levels of power or signal levels.
The project was designed with KiCad
This image can be transfered onto a 100mm x 50mm PCB and etched:
With this schematic you can assemble your circuit board onto a perf-board or a bread-board or whatever you prefer.
Note
The schematic is adapted from EM50205 from ELModules, so I don't claim it as my own - my contribution is rather the nice PCB and the pretty schematical layout that can help others learn or manufacture their own simple circuitboards.

The component values doesn't have to be exact in each case but in the ballpark of these:
