Have been working with RS485 since almost a decade now. Can handle this job pretty efficiently and I will use KiCad for it. Extensively used JLCPCB/LCSC so not a problem. Let me know. Thanks

@markoa7

Hi there, I’ve reviewed your 6-channel PIC RS-485 PCB brief and I can deliver a fabrication-ready layout suitable for JLCPCB/LCSC within a compact 50 × 100 mm outline. The design will center on a PIC microcontroller sampling six analog inputs with an isolated RS-485 link using the TD551S422H. I’ll provide a clean schematic and PCB files (KiCad or Altium), Gerbers, drill, and a BOM with LCSC part numbers and recommended alternates. Deliverables will emphasize manufacturability, trace impedance control, and a tidy ground/isolation strategy, with a ready-to-upload package for your board shop. What is the exact PIC model and input voltage ranges you plan for the analog channels, and do you require galvanic isolation on the power domain as well? Best regards, Marko Aleksic

A compact mixed signal PIC board only works well when the analog inputs and isolated RS 485 section are laid out with clear separation and clean return paths. Well, what I can do for you as an electronics engineer is design the full schematic and PCB for your PIC based six channel analog sampling board with an isolated RS 485 interface using the TD551S422H, keeping it compact and fully compatible with JLCPCB fabrication and assembly. In fact, I designed a high power 10000 watt LED dimmer for a UK client and I also built an 8 bit SAR ADC logic in Cadence, so I am comfortable with mixed signal layout discipline, component selection, and production ready PCB deliverables.

@yaroslavmark

Hello, I have designed 12+ compact mixed-signal boards using PIC microcontrollers, including 6 isolated RS-485 interfaces, with four successfully manufactured through JLCPCB without a single DFM revision; in one 8-channel ADC project, I reduced analog noise by 32% by optimizing ground partitioning and reference routing. I have also completed three sub-100 mm boards (smallest 48 × 85 mm) with controlled differential impedance and verified creepage distances above 6 mm for reinforced isolation. For this project, my approach will be: (1) define power architecture, ADC reference stability, and protection network based on your input ranges; (2) design schematic with LCSC-available components including isolation barrier implementation around the TD551S422H; (3) perform PCB layout with strict analog/digital partitioning, controlled RS-485 differential impedance, and verified creepage/clearance; (4) run DRC/DFM checks aligned with JLCPCB capabilities and generate fabrication, assembly, and BOM files. Could you confirm the exact PIC part number and ADC resolution requirement? What are the analog input voltage/current ranges and expected sampling rate? What isolation voltage and surge immunity level are required? Will the board be powered externally or through the RS-485 side? I am ready to start immediately upon receiving the pin-out and constraints.
