README
README.mdAvr ZIFF Programmer
This simple utilitarian board makes use of a Ziff Socket and AVR ICSP headers to enable the programming of four different
- ATtiny85
- ATtiny84
- ATtiny2313
- ATmega328
It also has a FTDI adapter that works with the ATmega328
very handy for flashing a bunch of chips to put in kits.

Questions
How big is the AvrZiffProgrammer PCB?
It measures 61 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AvrZiffProgrammer use?
13 parts. 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 AvrZiffProgrammer KiCad files?
From the UserHackable/Avr_Ziff_Programmer repository on GitHub, at the commit this page was made from: the board is KiCad/AvrZiffProgrammer/AvrZiffProgrammer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AvrZiffProgrammer design in my own project?
Its repository states no licence, so its author keeps all rights: ask UserHackable before reusing the design.
