🔌 Hardware Wiring (XIAO to MicroSD Breakout)

Wire the 6 pins between your Seeed Studio XIAO ESP32-C6 and standard SPI MicroSD card module:

MicroSD Pin XIAO ESP32-C6 Pin Function Wire Color (Typical)
VCC 3V3 3.3V Power Red
GND GND Ground Black
SCK / CLK D8 (GPIO 19) SPI Clock Yellow
MISO D9 (GPIO 20) SPI Master In / Slave Out Green
MOSI D10 (GPIO 18) SPI Master Out / Slave In Blue
CS D2 (GPIO 2) SPI Chip Select White
Pro Tip: If your Xiao COM port doesn't appear in the browser list, hold down the tiny physical BOOT button on the Xiao while plugging the USB-C cable into your computer. This forces the ESP32-C6 into native ROM bootloader mode.
