George 1.5 HandPCB Right is an open-source printed circuit board by MathiasSmith2002, from the MathiasSmith2002/Hand_PCBs repository on GitHub. It is a 2-layer board of 55 × 53 mm with 11 parts on 3 nets.
It measures 55 × 53 mm and has 2 copper layers, 1.6 mm thick.
11 parts. 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.
From the MathiasSmith2002/Hand_PCBs repository on GitHub, at the commit this page was made from: the board is George_1.5_HandPCB/George_1.5_HandPCB_Right.kicad_pcb and its schematic George_1.5_HandPCB/George_1.5_HandPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask MathiasSmith2002 before reusing the design.
