Questions
How big is the 1u panel v1 PCB?
It measures 83 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 1u panel v1 use?
75 parts, built around the STM32F091CCT7, INA226AIDGSR, LTC4412ES6#TRPBF and CL10B104KB85PND. 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 1u panel v1 KiCad files?
From the BrownSpaceEngineering/PVDX-Solar_PCB repository on GitHub, at the commit this page was made from: the board is 1u_panel-v1.kicad_pcb and its schematic 1u_panel-microcontroller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 1u panel v1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask BrownSpaceEngineering before reusing the design.
