Custom 12V DC Power Management PCB — Rugged Field Hardware (JLCPCB)

Title: Custom 12V DC Power Management PCB — Rugged Field Hardware (JLCPCB) Description: I'm building a rugged field hardware product called the BOB Air Command — a portable command center for drone pilots and field professionals. I need a compact 12V DC power management PCB designed for a corner-mounted housing inside a Nanuk case. Board Spec: 12V DC input via barrel jack P-channel MOSFET reverse polarity protection Auto-reset PTC fuse for overcurrent protection Eagle Eye 19mm illuminated push button (white LED) — main power on/off Output 1: Screw terminals to external marine USB socket (USB-C x2, USB-A x2) Output 2: 12V out to dedicated push button → external USB-C PD converter (~25W max) for field monitor Output 3: 12V screw terminals reserved for future expansion All external connections via screw terminals or panel-mount connectors Must fit compact corner unit housing — small form factor required Deliverables: Schematic PCB layout (Gerber files) BOM with JLCPCB parts where possible Pick-and-place file Brief wiring/assembly notes Ideal candidate: Experience with 12V automotive or field power systems. Please include samples of similar low-voltage power distribution PCB work. Looking for a long-term PCB design partner as this product line grows. Manufacturing target: JLCPCB prototype run.
