Timeline: 1week, Budget: 600USD Sampels: i could provide when chatting as i can't upload images here. Hello, I’m an embedded hardware and electronics engineer with 7+ years of experience designing production-grade PCBs for harsh environments, including automotive, EV, and industrial IoT systems, and I’ve carefully reviewed your eBike telemetry requirements. I’ve completed 20+ multi-layer PCB designs, including 6 projects operating on 48–72V battery systems, where EMI, vibration, and moisture resistance were critical design constraints. For this project, I would design a robust power front-end (reverse polarity, fuse, TVS, LC filtering) followed by high-efficiency buck regulation (>90%) to stable 5V and 3.3V rails suitable for ESP32 and sensitive sensors. I have hands-on experience integrating ESP32 (WROOM & S3) with cellular modules, and I’ve shipped boards using INA226, SHT31, DS18B20, and analog water-sensing circuits in electrically noisy environments. My PCB approach includes proper grounding, controlled impedance where needed, EMI mitigation, vibration-safe footprints, and connector selection suitable for e-bike enclosures. I regularly deliver schematics, PCB layouts, Gerbers, Pick & Place, BOMs with verified part numbers, and PDF documentation, using KiCad or Altium, ready for third-party manufacturing. T

Hi, I am an Electronics Engineer specializing in Power Management and Embedded Systems. I have experience designing high-current DC boards and am fully equipped to handle the electrical noise and voltage transients of a 60V E-Bike environment. My Technical Approach: HV Power Stage (Critical): A "60V" e-bike battery often spikes to 80V+ during regenerative braking. A standard buck converter will explode. I will design a 100V-rated power stage (using TI/Analog Devices automotive regulators) with High-Energy TVS diodes and Polyfuses to clamp transients, ensuring the MCU never fries. ESP32 & 4G Integration: Since the ESP32 lacks native LTE, I will integrate a robust UART Modem (like the SIM7600 or A7670 series) directly onto the PCB. I will design the power rails specifically to handle the 2A current bursts that 4G modems draw, ensuring the system never resets during data upload. Noise & Robustness: I2C Protection: Motor controllers generate massive EMI. I will add proper filtering on the SHT31/INA226 lines to prevent bus lockups. Mechanical: I will specify Locking Connectors (Molex Micro-Fit or JST-JWPF) to withstand vibration. Deliverables: KiCad Source Files. BOM (Focusing on AEC-Q Automotive grade parts). Gerbers optimized for manufacturing. I am ready to sign the NDA and start immediately.

✅Okay, I got what you want exactly. I am a senior electronics and embedded systems engineer with over 10 years of experience, providing ESP32-based hardware design, high-voltage power electronics, EMI/ESD protection, and production-ready PCB layout for harsh environments. In my opinion, the key to this project is a clean power architecture and noise-resilient layout that can survive motor switching spikes, vibration, and moisture without sacrificing ESP32 RF performance. I would focus on proper input protection, wide creepage, grounding strategy, and component selection that is proven in light automotive systems. This project is very similar to my previous works. I recently designed a 72V lithium telemetry and safety board using ESP32-S3 with INA22x current sensing, multi-sensor I2C buses, and automotive TVS protection, deployed in over 300 units. I handled schematic capture, 6-layer PCB layout, connector selection, and delivered full Gerbers, PnP, and BOM ready for contract manufacturing. ✅ So, I will divide your project like following: ⚡ System architecture & component selection ⚡ Robust power input, protection, and EMI design ⚡ ESP32 + sensor schematic and PCB layout ⚡ Manufacturing files, BOM, and design notes Via private chatting or meeting, I will provide the creative idea and solid technical solution for your project, and I’d be happy to discuss budget and timeline in detail.
