6-Channel PIC RS485 PCB (HW only)
Budget: $30 – $250 USD
I’m putting together a compact board and need a design that JLCPCB can fabricate without revisions.
The core is a PIC microcontroller sampling six analog inputs; the data must leave the board through an isolated RS-485 link implemented with the TD551S422H.
The outline will be approx 50 mm × 100 mm range.
I will share the exact pin-out, input ranges, and connector locations once we start; everything else—from component selection inside the JLCPCB/LCSC ecosystem to trace impedance and isolation barriers—will be yours to define.
Here’s what I expect at hand-off:
• Schematic and PCB files (KiCad or Altium, your choice)
• Gerber, drill, and pick-and-place files ready for JLCPCB upload
• BOM with LCSC part numbers and any alternates you recommend
If you’ve done small-footprint mixed-signal PIC designs or isolated RS-485 links before, this should be straightforward. Let me know your preferred toolchain and any questions you need answered to get started.
