Questions
How big is the AbsoluteEncoderBoard PCB?
It measures 49 × 59 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AbsoluteEncoderBoard use?
120 parts, built around the STM32F405RGT6, MAX485ED, MCP2551-I/P and MCP2551-I/SN-HG. 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 AbsoluteEncoderBoard KiCad files?
From the SamsonChau/PCB repository on GitHub, at the commit this page was made from: the board is other/AbsoluteEncoderBoard_v4.1_20210507/AbsoluteEncoderBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AbsoluteEncoderBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask SamsonChau before reusing the design.
