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.
