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.

Based on the name and usual conventions, "TOUCH4_GPIO4_A3_D3" seems to be a multi-functional pin on the Seeed Studio XIAO ESP32S3 device.
  1. "TOUCH4": Indicates that it can function as capacitive touch input number 4. Capacitive touch functionality allows the device to sense touch without needing physical pressure. Primarily used in touch-interface devices (e.g. touchscreens).
  2. "GPIO4": Suggests this is General Purpose Input/Output (GPIO) pin number 4. GPIO pins can be programmed to either send (output mode) or receive (input mode) digital signals.
  3. "A3": Usually represents,"Analog input channel 3". Analog inputs read voltage levels and usually connect to sensors or similar devices.
  4. "D3": Typically implies "Digital I/O pin number 3". Digital I/Os are used for communication with other digital circuits.
It's important to note that you can only use one function of the pin at a time, and the pin's function is assigned programmatically.
Remember to check the specific device's datasheet or documentation to confirm the specific properties and capabilities of each pin.
