README
dishy1pi/README.mdDishy1Pi Hardware
The hardware part of the Dishy1Pi project is a Raspberry Pi Hat board which interfaces the Raspberry Pi GPIO pins with the satellite dish motor controllers, encoders, and various sensors. An important aspect of this board is that the Raspberry Pi is optically isolated from the hardware connected to the satellite dish.
Although this project is tailored to controlling a satellite dish, it can also be used for controlling other motor control systems that require isolation and encoder feedback.
Parts Library
The PCB will be assembled by JCLPCB. The project will require parts number identification to be compatible with LCSC part numbers. See Library README

Questions
How big is the Jrdish axis controller PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Jrdish axis controller use?
248 parts, built around the STM32G474RET6, ISOW1432BDFMR, MAX-M10S-00B and MP2322GQH-Z. 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 Jrdish axis controller KiCad files?
From the jrseti/pcbs repository on GitHub, at the commit this page was made from: the board is jrdish_axis_controller/jrdish_axis_controller.kicad_pcb and its schematic dishy1pi/DishyPi1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Jrdish axis controller design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
