My ESP32 Wi-Fi development module for the Flipper Zero lost its header pins and I need them professionally re-soldered so it can slot back onto the Flipper’s GPIO rail without wobble or mis-alignment. This is a personal hobby project, not a commercial job. I don’t have replacement headers on hand, so please supply a fresh, standard-pitch male header strip that matches the original footprint. If you normally work with low-profile or gold-plated variants, feel free to use those as long as they fit the stock socket height. Beyond that, there are no special instructions that I’m aware of—just clean joints, proper alignment, and a quick continuity check to confirm every pin is live after reassembly. If you like to flux-clean or heat-shrink for strain relief, that’s fine. Deliverable: • The ESP32 board returned with new headers firmly attached and tested for continuity across all pins. Let me know your estimated turnaround time and the shipping details you’ll need.

⭐⭐⭐⭐⭐ I can handle the header replacement and make sure the ESP32 Wi-Fi board mates cleanly with the Flipper Zero GPIO rail without wobble or alignment issues. I’ll use a new standard-pitch male header matching the original footprint and socket height, then carefully align and solder it so the pins remain straight and perpendicular to the PCB. I’ll use appropriate flux and controlled heat to avoid damaging nearby components or lifting pads. After soldering, I’ll: • Inspect every joint under magnification • Verify header alignment and mechanical fit • Perform continuity checks across all pins • Check for unintended shorts between adjacent pins • Clean the board and provide confirmation before return Estimated turnaround: [YOUR TURNAROUND] after receiving the board. For shipping, I would need the delivery address and preferred shipping method. I can also confirm the exact header specification from photos or the board before ordering the replacement part. This is a small rework job, but I’d treat the alignment and final electrical inspection just as carefully as a production repair.

Hi there, Misaligned or poorly soldered header pins on your ESP32 module will ruin the physical connection to your Flipper Zero, leading to intermittent power drops and data corruption. I will professionally install and solder a fresh, high-quality male header strip onto your board, ensuring perfectly perpendicular alignment. Relying on my background in precision PCB assembly and hardware troubleshooting, I will provide clean, reliable solder joints, perform a thorough flux cleanup, and conduct rigorous continuity checks so the module slots flawlessly into your Flipper’s GPIO rail. I have two quick questions to make sure we’re on the same page: Do you prefer standard tin-plated headers, or should I source gold-plated ones for better long-term contact reliability? Are there any other components or traces on the module that were damaged when the original headers broke off that I should inspect? Let’s discuss your project now!
