@mykolalus

Hi, I recently designed a battery-powered IoT monitoring board using the ESP32 with remote sensors connected through cable harnesses. The main challenge was minimizing power consumption while maintaining reliable sensor readings and keeping the PCB simple and low-cost for manufacturing. From your description, you need a compact IoT board integrating an VL53L4CD Time-of-Flight sensor and a 10K NTC thermistor, with the sensors connected remotely via cables. The key considerations will be stable power management for a NiMH battery system, clean analog measurement for the thermistor, and reliable connectors such as JST‑PH for external sensor wiring. My approach would be: 1. Design a low-power schematic with ESP32, battery management, and sensor interfaces 2. Implement efficient voltage regulation suitable for NiMH battery operation 3. Create a compact PCB layout optimized for low-cost manufacturing 4. Add connectors for remote sensors and removable battery integration 5. Deliver full fabrication files (schematic, PCB, BOM, Gerbers) Quick question: Do you plan to use deep-sleep modes on the ESP32 to extend battery life, and what approximate battery capacity are you targeting? Best regards Mykola
