Arduino PCB Design (JLCPCB)

I’m putting together a personal project that centres on an Arduino-based control board populated with several sensors, and I want the entire schematic and PCB laid out so I can send it straight to JLCPCB for fabrication and assembly... (Budget: $10 - $30 USD, Jobs: Arduino, Circuit Design, Electrical Engineering, Electronics, Embedded Systems, PCB Layout, Prototyping, Sensor Integration)
