Questions
How big is the Viperv1 PCB?
It measures 50 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Viperv1 use?
27 parts, built around the ESP32-C6-MINI-1, LM1117MP-3.3, USBLC6-2SC6 and ESD9B3.3ST5G. 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 Viperv1 KiCad files?
From the asuperidea/viper repository on GitHub, at the commit this page was made from: the board is hardware/viperv1.kicad_pcb and its schematic hardware/viperv1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Viperv1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask asuperidea before reusing the design.
