Design a schematic for a portable environmental sensor device based on the Seeed XIAO ESP32S3. The system includes the following components: • Seeed XIAO ESP32S3 (I2C on GPIO5/SDA and GPIO6/SCL, SPI on GPIO7/SCK, GPIO8/MISO, GPIO9/MOSI, CS on GPIO4, I2S on GPIO1/GPIO2/GPIO3) • SPS30 particulate matter sensor (I2C 0x69, 5V powered) connected via JST ZHR-5 5-pin connector • SHT31 temperature and humidity sensor (I2C 0x44) • BH1750 light sensor (I2C 0x23) • DS3231 RTC (I2C 0x68) • ADXL345 accelerometer (I2C 0x53) • INMP441 I2S microphone (WS/GPIO1, SCK/GPIO2, SD/GPIO3, L/R to GND) • SD card module via SPI with 6-pin connector • MT3608 boost converter (3.7V to 5V) with external inductor, capacitors and feedback resistors for the SPS30 • LiPo battery 3.7V with slide switch on BAT+ line connected to XIAO BAT pin and MT3608 input Use net labels for I2C and SPI buses. Include decoupling capacitors on all sensor VCC pins.

    Polygon coordinates: (x1, y1), (x2, y2), (x3, y3), (x4, y4) — covering the ESP32S3 onboard module’s antenna edge. Referenced from the top right of the XIAO footprint: Width 7.0 mm, Height 5.5 mm. Affected layers: Top, Bottom, TopCopper, BottomCopper, TopSilkscreen, BottomSilkscreen, TopMask, BottomMask. Clearance: no copper/fills/traces/components allowed; keepout is for all layers. Final coordinates and reference to be documented per final XIAO footprint placement in layout documentation.
