Questions
How big is the Wombat2 PCB?
It measures 137.1 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wombat2 use?
134 parts, built around the TSB7191AILT, 2EDN7524FXTMA1, ADS1115IDGS and L7805. 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 Wombat2 KiCad files?
From the Rollpopptery/wombat2 repository on GitHub, at the commit this page was made from: the board is circuit/wombat2/wombat2.kicad_pcb and its schematic circuit/wombat2/wombat2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wombat2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Rollpopptery before reusing the design.
