Questions
How big is the Debugger PCB?
It measures 148.6 × 53.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Debugger use?
27 parts, built around the TEENSY 4.1 and SN74CBTLV3257PWR(LX). 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 Debugger KiCad files?
From the bmichini/nandirl repository on GitHub, at the commit this page was made from: the board is hardware/debugger/debugger.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Debugger design in my own project?
Its repository states no licence, so its author keeps all rights: ask bmichini before reusing the design.
