Questions
How big is the Rocket2-trs hardware PCB?
It measures 65.8 × 60.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rocket2-trs hardware use?
69 parts, built around the AP63205WU, SN74LVC1T45DCK, TLP3553A(TP1,F and AMS1117-3.3. 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 Rocket2-trs hardware KiCad files?
From the UCI-Rocket-Project/rocket2-trs-hardware repository on GitHub, at the commit this page was made from: the board is TRS-KICAD/rocket2-trs-hardware.kicad_pcb and its schematic TRS-KICAD/rocket2-trs-hardware.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rocket2-trs hardware design in my own project?
Its repository states no licence, so its author keeps all rights: ask UCI-Rocket-Project before reusing the design.
