Features / Specs

  • Manufacturer: Seeed Studio
  • Part Number: 113991115
  • Main Chip: Espressif ESP32-S3R8 (Xtensa 32-bit LX7 Dual-Core Processor, Up to 240 MHz)
  • Antenna: External FPC antenna (Seeed XIAO FPC Antenna A-02, included), connects to the onboard Male IPEX MHF-I / U.FL Socket (Hirose U.FL-R-SMT-1) – the board has no onboard antenna
  • Flash Memory: 8 MB (onboard GD25Q64ENIGR SPI flash)
  • ROM: 384 kB
  • SRAM: 512 kB (plus 16 kB RTC SRAM)
  • PSRAM: 8 MB Octal SPI (in-package, ESP32-S3R8)
  • USB Interface: USB Type-C, connected directly to the ESP32-S3’s native USB pins (USB Serial/JTAG controller and full-speed USB OTG) – no USB-to-UART bridge chip
  • Power Input Options:
    • USB Type-C Socket: 5 VDC
    • VUSB Pin: Power input/output, connected directly to the USB Type-C VBUS line – no voltage is present on this pin when running from the battery, and an external 5 V source must be connected through a series diode (anode on the source side)
    • Battery Pads: 3.7 V lithium battery, soldered to the BAT pads on the back of the board (no battery connector), charged by the onboard SGM40567-4.2 charger at about 110 mA
  • Power Switching: Runs from USB (or the VUSB pin) when connected, and from the battery otherwise – a diode stops the battery feeding back out of the VUSB pin
  • 3V3 Pin (Output): Regulated 3.3 V output from the onboard SGM6029 buck converter
  • Operating Voltage Range (Chip): 3.0 – 3.6 V (supplied at 3.3 V by the onboard regulator)
  • I/O Logic Level: 3.3 V – inputs are rated to a maximum of VDD + 0.3 V, so the pins are not 5 V tolerant
  • Standby Current (Typical): 3 mA (deep sleep, with the camera expansion board fitted)
  • Communication Interface: USB / UART
  • Programming Support: Arduino / MicroPython / SenseCraft AI (no-code vision and audio models)
  • Bootloader: Hold Boot while connecting USB (or hold Boot and press Reset) to enter bootloader mode
  • Operating Temperature Range: -20 °C to +65 °C
  • Usable Peripherals (This Board): 11x programmable GPIOs on the headers (all PWM-capable) / 1x UART (UART0 on D6 / D7) / 1x I2C / 1x SPI (shared with the microSD slot) / 1x I2S (used by the onboard microphone) / 9x ADC channels / 9x touch-sensing pins
  • Full Chip Capabilities (Not All Exposed on This Board): 45x programmable GPIOs / 4x SPI (2 reserved for flash/PSRAM access, 2 general-purpose) / 3x UART / 2x I2C / 2x I2S / 2x 12-bit SAR ADC, up to 20 channels / 14x capacitive touch IOs / full-speed USB OTG + USB Serial/JTAG / TWAI (CAN 2.0) / LED PWM (up to 8 channels) / 2x MCPWM / RMT / PCNT / SD/MMC host (2 slots) / LCD interface / 8-bit to 16-bit DVP camera interface
  • GPIO:
    • Usable: 11x programmable GPIOs on header pins D0 – D10 (GPIO1 / GPIO2 / GPIO3 / GPIO4 / GPIO5 / GPIO6 / GPIO43 / GPIO44 / GPIO7 / GPIO8 / GPIO9)
    • Analog / Touch: D0 – D5 and D8 – D10 (9x ADC1 channels, also capacitive touch)
    • Used by Camera: GPIO10 – GPIO18 / GPIO38 / GPIO39 / GPIO40 / GPIO47 / GPIO48 – through the B2B connector, not on the headers
    • Used by microSD: GPIO21 (CS, shared with the user LED) plus the header SPI pins D8 / D9 / D10 (GPIO7 / GPIO8 / GPIO9); cutting the J3 pad on the expansion board disconnects the card’s pull-up resistors – the header SPI pins then work normally and the card slot is disabled
    • Used by Microphone: GPIO42 (PDM clock) / GPIO41 (PDM data), also brought out to the D11 / D12 pads on the expansion board; cutting J1 / J2 frees them for other uses but disables the microphone (these two pins have no ADC)
    • Series Resistor: D6 (TX) connects to the chip through a 499 Ω resistor – fine for UART, but it limits the current D6 can supply
    • Reserved for Flash/PSRAM: GPIO26 – GPIO32 (flash/PSRAM SPI bus) / GPIO33 – GPIO37 (Octal PSRAM) – internal, not broken out; Espressif says not to use them for any other purpose
    • Shared with USB: GPIO19 / GPIO20 – native USB D- / D+, wired to the USB Type-C socket and to the D- / D+ pads on the back of the board, not to the headers
    • Strapping Pins: GPIO0 (BOOT button) / GPIO3 (header pin D2) / GPIO45 / GPIO46 (not broken out, left at their internal defaults) – sampled at reset
    • Battery Monitoring: None – no GPIO is wired to read the battery voltage
    • Debug: USB Serial/JTAG over the USB Type-C port, plus JTAG pads on the back of the board (MTDO / MTDI / MTCK / MTMS / EN / GND) – the JTAG pins are GPIO39 – GPIO42, shared with the camera and microphone
  • Onboard Peripherals:
    • Camera: Detachable camera module on the expansion board (DVP interface) – OV3660 (3 MP, 2048 x 1536, fixed focus)
    • Microphone: Digital PDM MEMS microphone (MSM261D3526H1CPM) on the expansion board
    • microSD Card Slot: On the expansion board, SPI mode, supports cards up to 32 GB (FAT)
    • Buttons: Reset / Boot
    • LEDs: Yellow user LED on GPIO21, lit when driven low (shared with the microSD CS) / red charge LED
  • Pin Description: Pinout diagram in the product images; full pin map in the linked Seeed wiki
