2019 edition of a breadboard USBasp AVR programmer
This is just a quick upload place for my project around an USBasp AVR programmer based on the circuit used by Thomas Fischl, but easily placeable on a standard breadboard.
The necessary gerber files for pcb manufacturing can be found in the folder "production"
A plan could be to merge the hardware layout with another firmware like https://github.com/mariusgreuel/USBasp
The original firmware from Thomas Fischl can be used https://www.fischl.de/usbasp/

Questions
How big is the 20190811 usbasp PCB?
It measures 53.3 × 34.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 20190811 usbasp use?
41 parts, built around the ATMEGA88-20AU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the 20190811 usbasp KiCad files?
From the uwezi/2019_USBasp repository on GitHub, at the commit this page was made from: the board is kicad/20190811_usbasp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 20190811 usbasp design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
