Questions
How big is the CAR RX PCB?
It measures 60 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CAR RX use?
91 parts, built around the RP2354A, A3901SEJTR-T, W25Q128JVSIQ and LM1117MP-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 CAR RX KiCad files?
From the Gurtej2709/RC-CAR-TOY-RX repository on GitHub, at the commit this page was made from: the board is CAR RX.kicad_pcb and its schematic CAR RX.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CAR RX design in my own project?
Its repository states no licence, so its author keeps all rights: ask Gurtej2709 before reusing the design.
