Questions
How big is the Enc encoder PCB?
It measures 40 × 40 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Enc encoder use?
87 parts, built around the RP2350A, SP3485CN-L, W25Q128JVSIQ and OQ0232510000G. 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 Enc encoder KiCad files?
From the ROAR-QUTRC/perseus-v3 repository on GitHub, at the commit this page was made from: the board is hardware/enc-encoder/enc-encoder.kicad_pcb and its schematic hardware/dc-motor-driver/RS485.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Enc encoder design in my own project?
Its repository states no licence, so its author keeps all rights: ask ROAR-QUTRC before reusing the design.
