Milano Smart Park Hardware

Hardware PCB files for the ESP32-based Milano Smart Park project

Note: The PCB v7 files are old and deprecated. New design files need to be made to better represent the current state of the project!

  • ESP32-DevkitC with ESP32-WROVER-B module with attached:

    • OLED Display SH1106 1.3" 128X64 (IIC)
    • SD Card Module
    • SIM800L 2G Modem (Serial)
    • Adafruit's BME680 sensor (IIC)
    • Plantower's PMS5003 Air Quality sensor (Serial)
    • seeed's Grove Multichannel Gas Sensor MiCS-6814 v1.0 (IIC) (With custom modifications)

Quick schematic of the ESP32 /w WROVER-B devkit:
