Questions
How big is the New worm3 PCB?
It measures 56.4 × 108.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the New worm3 use?
94 parts, built around the STM32F405RGT6, LM1117-3.3V and LM1117-5V. 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 New worm3 KiCad files?
From the microresearch/WORM repository on GitHub, at the commit this page was made from: the board is revival/new_worm3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the New worm3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask microresearch before reusing the design.
