Questions
How big is the ORB PCB?
It measures 104 × 72 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ORB use?
141 parts, built around the STM32F405VGT6, TB6612FNG,C,8,EL, RN4678-V/RM113 and C0805C104K5RAC7800. 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 ORB KiCad files?
From the ThBreuer/ORB-Hardware repository on GitHub, at the commit this page was made from: the board is Ver-01.xx/KiCad/ORB.kicad_pcb and its schematic Ver-01.xx/KiCad/Controller_Bluetooth.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ORB design in my own project?
Its repository states no licence, so its author keeps all rights: ask ThBreuer before reusing the design.
