t Port, we develop e-bike and e-mobility docking stations. As part of our system, our bikes are equipped with a custom connector that integrates: • ESP32 • Electronics for power & data handling • LIN communication
We have ~60 connectors that require diagnostics and repairs. Based on our investigation, we have identified two main failure types: 1. Flash corruption – can be fixed by reprogramming the ESP32. 2. ESP failure – requires re-soldering the ESP32 module.
However, there may be other issues that require deeper analysis and troubleshooting.
Your Responsibilities • Diagnose faulty connectors to determine root causes. • Reprogram ESP32-based units where needed. • Re-solder and replace ESP32 modules for failed units. • Identify other potential issues and document findings. • Ensure repaired units are fully functional and communicate over LIN.
Requirements • Strong experience with ESP32 development & troubleshooting • Hardware debugging skills (soldering, PCB repair, fault analysis) • Familiarity with LIN communication (or willingness to learn) • Access to necessary tools (e.g., hot air station, oscilloscope, programmer) • Ability to work independently and provide detailed reports
Additional Information • Location: Remote (hardware can be shipped) pick up and drop off ideally LONDON. • Budget: success fe based depending on the conector fixed 25-40GPB based on expirence and other circumstances like time to completion . • Delivery: Work needs to be completed efficiently with a structured approach to diagnosis and repair.
If you have experience with ESP32 and hardware debugging and are confident in tackling this task, we’d love to hear from you!
