Questions
How big is the Usbasploader PCB?
It measures 28.9 × 35.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usbasploader use?
22 parts, built around the ATMEGA8A-AU. 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 Usbasploader KiCad files?
From the mekatronik-achmadi/atmega-dev repository on GitHub, at the commit this page was made from: the board is atmega-demos/avr_usbasp/circuit/kicad/usbasploader/usbasploader.kicad_pcb and its schematic atmega-demos/avr_usbasp/circuit/kicad/usbasp/usbasp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usbasploader design in my own project?
Its repository states no licence, so its author keeps all rights: ask mekatronik-achmadi before reusing the design.
