I HAVE DONE SOMETHING SIMILAR BEFORE! Your need for a clean, professional, and seamless PCB design that integrates multiple power sources—LiPo, Li-ion, LiFePO4 batteries, USB, and solar MPPT charging—with switchable dip settings is clear. The challenge of ensuring the board can both supply power and monitor battery voltage via Meshtastic firmware shows your focus on user-friendly, automated functionality. With expertise in embedded systems, power management circuits, and Arduino integrations, I can diagnose and fix power routing issues on your board. Having reviewed your project scope, including Gerber files and BOM, I’m confident in delivering an integrated and automated solution that restores full functionality to all power ports and jumper settings. You won’t find someone more aligned with what you’re looking for. Come chat with me, worst case you get a free consultation :) Regards, Lee-Wayde

Hi, I am an Electronics Engineer specializing in multi-layer PCB design, hardware debugging and power management circuits. I read your project details carefully and it seems like a classic power path routing, net naming mismatch or protection isolation issue where none of your input/output power nodes are bridging to the main regulator rails. Handling multi-chemistry batteries (LiPo, LiFePO4) alongside MPPT solar charging and switchable jumper ports requires precise power-rail isolation. I have extensive experience resolving such hardware issues and generating production-ready hardware revisions. Since you already have the complete manufacturing package (Gerbers, Schematics, BOM, and Positions CSV), I can immediately audit your Kicad design files, trace the broken power path, fix the schematic and provide you with an updated, flawless revision ready for JLCPCB. Please share the zip file so I can review the schematics and pinpoint the exact issue. Looking forward to fixing this board for you! Best regards, Raja Huzaifa

⭐⭐⭐⭐⭐ I have strong experience in PCB design, power management circuits, battery charging systems, and embedded hardware debugging, and I can help identify and resolve the issues with your current Meshtastic/Arduino board. Based on your description, the problem is likely related to the power-path design, switching configuration, routing, or charging circuitry around the DIP switches, jumper ports, and battery management section. Since you already have the full project package including Gerbers, BOM, placement files, and working manufactured boards from JLCPCB, I can efficiently review the design, trace the fault, implement the required fixes, and prepare corrected production files for reliable operation with LiPo, Li-ion, LiFePO4, USB charging, solar MPPT input, and shared power functionality. I look forward to helping you bring the board to full working condition.

I read your project description carefully. It is great that your logic side (Arduino + Meshtastic) is communicating on the mesh, but the fact that all power sources (Battery, Solar MPPT, USB, and Jumper) are failing indicates a critical design flaw in the power distribution network. As an R&D hardware engineer specializing in power electronics, SMPS, and IoT telemetry boards, debugging complex power paths is my daily routine. I frequently design multi-layer boards using tools like EasyEDA and Altium, and I know exactly where these power delivery bottlenecks hide. Here is how I will tackle your board's issues: ower Muxing & IC Check: Analyze the charge controller and MPPT circuitry to find why power dead-ends before the main bus. DIP Switch Routing: Verify the resistor networks connected to the DIP switches to ensure voltage thresholds for LiPo, Li-ion, and LiFePO4 trigger the correct charging states. Jumper Port Continuity: Re-route the ports to ensure they safely supply and receive power without isolating the board. While having Gerbers, BOM, and CPL from JLCPCB is great for production, reverse-engineering raw Gerbers is inefficient. Do you have the original EDA source files (EasyEDA, Altium, etc.) containing the schematic? Please share the files. I will do a quick preliminary review and tell you exactly what went wrong and how fast we can get a fully functional revision to JLCPCB.
