ESP32 IoT Debugging Specialist in Namibia

@mairajali11

As a seasoned Electrical/Electronics Engineer with a keen interest in PCB design and perhaps most vital, well-over 8 years of professional experience, rest assured that your ESP32 IoT debugging project revolves around many elements where I excel. These include PCB design and prototyping using Eagle, Altium, KiCAD, EasyEDA – all platforms extensively used in this project. In my career span, I have also worked on various similar projects that involved debugging complex custom PCBs integrated with Li-ion/LiPo battery charging circuits, embedded firmware, sensors and diverse communication interfaces (SPI/I2C/UART). The test equipment I have access to including multimeters, oscilloscopes and bench power supplies will be instrumental to accurately inspecting and isolating the root cause of the hardware issue. Being a top-rated Namibian freelancer based in Windhoek, am more than just geographically advantageous for this task I can also physically receive and test the device to swiftly identify intermittent or permanent failures and suggesting/implementing hardware modifications where needed. My hourly rate is reasonable too for such a hyper-focused hands-on engineering project of this scope. Trust my expertise to make it worth hiring me! As an added convenience, I am capable of receiving any details: schematics, PCB files, firmware and device information that you will provide! So why not go ahead with a professional who has always delivered RESULTS?

tom PCB debugging, power management, sensors, RS485, UART/I2C/SPI, and PCB bring-up. I can physically inspect and debug the device if it can be couriered to my location in India. I have access to a multimeter, oscilloscope, bench power supply, and PCB rework tools. I can diagnose the root cause, implement hardware fixes, and test the device after repair. Happy to discuss the project.

Hi, I’m interested in helping troubleshoot your ESP32-based IoT device and can handle systematic hardware/firmware diagnosis. Location: [Your city, Namibia] Qualification: [Your electronics/engineering qualification] Physical device testing: [Yes/No] My experience includes: • ESP32 boot and power debugging • Custom PCB troubleshooting • Li-ion/LiPo charging and power circuits • RS485, UART, SPI and I2C debugging • Sensor/display fault diagnosis • Firmware and configuration checks • Multimeter/oscilloscope-based testing • Soldering and PCB rework • Intermittent fault/root-cause analysis My workflow is to inspect the board, verify power rails/current draw, check ESP32 boot/reset signals, test communication buses and peripherals, review firmware logs, isolate the failing subsystem, then document and verify the repair. Test equipment available: [Multimeter / Oscilloscope / Bench PSU / Soldering station] Rate: ₹1,000/hour Typical turnaround: 1–3 days depending on fault complexity. I can also provide a concise diagnostic report covering the root cause, measurements, repair performed, and final test results. Best regards Ankit
