Features / Specs

Manufacturer: Seeed Studio
Part Number: 102010611
Kit Contents: XIAO ESP32-S3 board + Wio-SX1262 LoRa extension board (B2B connector version)
Main Chip: Espressif ESP32-S3R8 (Xtensa LX7 32-bit dual-core processor, up to 240 MHz)
Antenna:
- WiFi / Bluetooth: Male IPEX MHF-I / U.FL Socket (Hirose U.FL-R-SMT-1) on the XIAO ESP32-S3, for the included Seeed XIAO FPC Antenna A-02 (2.4 GHz) – no onboard antenna
- LoRa: Male IPEX MHF-I / U.FL Socket on the Wio-SX1262, for the included Seeed XIAO FPC Antenna A-03 (860 – 930 MHz)
- Note: Seeed describes the included FPC antenna as for testing only and recommends a separate external antenna for reliable use
Flash Memory: 8 MB (onboard, Quad SPI, GD25Q64ENIGR)
ROM: 384 kB
SRAM: 512 kB (plus 16 kB RTC SRAM)
PSRAM: 8 MB (in-package, Octal SPI)
USB Interface: USB Type-C, connected directly to the ESP32-S3’s native USB (USB Serial/JTAG controller and full-speed USB OTG) – no USB-to-serial chip
Power Input Options:
- USB Type-C Socket: 5 V
- 5V Pin: Power input/output, connected directly to the USB Type-C VBUS line – no voltage on it when running from the battery; to feed 5 V in, fit a diode (Schottky, signal or power), anode to the source and cathode to this pin
- 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 5V pin) when connected, and from the battery otherwise – a diode stops the battery feeding back out of the 5V pin
3V3 Pin: Regulated 3.3 V output from the onboard SGM6029 buck converter, up to 600 mA (Seeed schematic note)
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
Deep Sleep Current (Typical): 14 μA (XIAO ESP32-S3 board alone, 3.8 V battery supply) – Seeed publishes no figure for the assembled kit
Communication Interface: USB / UART
Programming Support: Meshtastic (pre-flashed) / Arduino / MicroPython
Meshtastic Firmware: Pre-flashed on the XIAO ESP32-S3; to reflash, choose the “Seeed XIAO S3” target in the Meshtastic web flasher
Bootloader Mode: Hold Boot while connecting USB, or hold Boot and press Reset
Operating Temperature Range: -40 °C to +65 °C
Usable Peripherals (This Board): 11x programmable GPIOs (all PWM-capable) / 1x UART (UART0 on D6 / D7) / 1x I²C / 1x SPI (shared with the Wio-SX1262) / 1x I²S / 9x ADC channels / 9x capacitive touch channels
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
Security Features (Chip): Secure boot / flash encryption / 4 kbit eFuse (OTP) / AES, SHA, RSA and HMAC acceleration / digital signature / random number generator
GPIO:
- Usable: 11x programmable GPIOs on header pins D0 – D10 (GPIO1 / GPIO2 / GPIO3 / GPIO4 / GPIO5 / GPIO6 / GPIO43 / GPIO44 / GPIO7 / GPIO8 / GPIO9)
- Analog: D0 – D5 and D8 – D10 (9x ADC channels)
- Touch: D0 – D5 and D8 – D10 (9x capacitive touch channels)
- Strapping Pins: GPIO0 (Boot button) / GPIO3 (D2) / GPIO45 / GPIO46 (not broken out, left at their internal defaults) – sampled at reset to set the boot mode, flash voltage and JTAG source, so keep external circuits from pulling them the wrong way at power-up
- Used Onboard: GPIO26 – GPIO32 (flash / PSRAM SPI bus) / GPIO33 – GPIO37 (Octal PSRAM) – not broken out; Espressif says not to use them for any other purpose
- Used by Wio-SX1262: SPI on the header pins D8 / D9 / D10 (GPIO7 / GPIO8 / GPIO9), plus GPIO41 (NSS) / GPIO39 (DIO1) / GPIO42 (reset) / GPIO40 (busy) / GPIO38 (RF switch) / GPIO21 (user button) / GPIO48 (green LED) – through the B2B connector
- Series Resistor: D6 (TX) connects to the chip through a 499 Ω resistor – fine for UART, but it limits the current D6 can supply
- Shared with USB: GPIO19 / GPIO20 (USB D- / D+) – used by the USB Type-C port, not on the headers; also on the D- / D+ pads on the back
- 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 (MTMS / MTDI / MTCK / MTDO; also EN / GND) – the JTAG pins are GPIO39 – GPIO42, used by the Wio-SX1262
Onboard Peripherals:
- Buttons: Reset / Boot (GPIO0) on the XIAO / user button on the Wio-SX1262 (GPIO21, reads low when pressed)
- LEDs: Yellow user LED on GPIO21, lit when driven low (shared with the Wio-SX1262 user button) / red charge LED / green LED on the Wio-SX1262 (GPIO48, lit when driven high)

Compatibility: The kit’s Wio-SX1262 plugs into the XIAO ESP32-S3’s B2B connector – the same connector the XIAO ESP32-S3 Sense camera board uses, so the two can’t be fitted at the same time. Seeed states the Wio-SX1262 from the XIAO nRF52840 kit is not compatible with the XIAO ESP32-S3.
