Raspberry Pi CAN HAT & Enclosure
Budget: $250 – $750 USD
I’m looking for a hardware designer who can deliver a complete, ready-to-manufacture solution that lets a Raspberry Pi Zero W talk to three independent, galvanically isolated CAN 2.0 networks and run safely from an industrial power rail.
Electronics scope
• Design a Pi HAT with three isolated CAN 2.0 ports.
• Each channel must exit the enclosure on its own RJ45 connector.
• On-board wide-input (12 V – 60 V DC) converter that powers both the Pi and the transceivers, with the appropriate isolation barriers in place.
• Provide schematics, PCB layout (KiCad or Altium), Gerbers, and a complete BOM with in-stock parts.
• Include any device-tree overlay, configuration, or test script needed to bring up the interfaces on Raspberry Pi OS.
Assist with a JBLPCB or similar service to get prototype PCBs made and assembled (design with in-stock parts).
Mechanical scope
• Design a compact plastic housing that fits the Pi Zero W plus HAT.
• Front panel: three RJ45 cut-outs; rear/side: a single power jack.
• Integrate vents and standoffs; leave clearance for header pins and cable strain relief.
• Add simple wall-mount points (key-hole slots or flanges).
• Supply 3D CAD (STEP) and print-ready STL files, plus a dimensioned drawing for future injection-mould tooling.
Acceptance
I will assemble and test the first prototype; please plan for one round of tweaks based on practical feedback.
If you’ve built isolated CAN hardware before—especially with parts like the ISO1050 or MCP2561—let me know. A brief outline of your approach, preferred toolchain, and estimated timeline will help me choose the right person quickly.
