You want an ESP32-S3 air-quality logger with dual SPS30, BME680, OPC-N3, microSD, RTC, and a SIMCom 2G–5G module. I’ve prepared a plan that’s ready to run:
  1. Core and comms: add ESP32-S3, SIMCom cellular module, nano‑SIM holder, MicroSD Card Socket, RTC, and USB‑C.
  2. Sensors: add connectors for two SPS30, one BME680, and OPC-N3; choose I2C/UART per device.
  3. Power: create 5 V and 3.3 V rails sized for Wi‑Fi and cellular peaks (>200 mA), plus EMI/ESD protection.
  4. Wiring/layout: assign SPI/I2C/UART, add 4.7k I2C pull‑ups and keep total bus capacitance ≤ 400 pF, route with RF keep‑outs and decoupling.
  5. Verify/release: run ERC/DRC, check part availability, generate BOM and manufacturing files.

  • Generic Capacitor
    Generic Capacitor
    A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
