Questions
How big is the EPROM programmer PCB?
It measures 139.7 × 139.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EPROM programmer use?
110 parts, built around the ATMEGA1284-PU, LM358, MC34063AP and MCP4812-E/P. 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 EPROM programmer KiCad files?
From the TheWaffleGuy/EPROM-programmer repository on GitHub, at the commit this page was made from: the board is EPROM-programmer.kicad_pcb and its schematic EPROM-programmer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EPROM programmer design in my own project?
Its repository states no licence, so its author keeps all rights: ask TheWaffleGuy before reusing the design.
