特点
  • Same size, form-factor, and pin-out as our SAMD-based QT Py
  • USB Type C connector - If you have only Micro B cables, this adapter will come in handy!
  • RP2040 32-bit Cortex M0+ dual-core running at ~125 MHz @ 3.3V logic and power
  • 264 KB RAM
  • 8 MB SPI FLASH chip for storing files and CircuitPython/MicroPython code storage. No EEPROM
  • Native USB supported by every OS - can be used as USB serial console, MIDI, Keyboard/Mouse HID, even a little disk drive for storing Python scripts.
  • Can be used with MicroPython or CircuitPython
  • Built-in RGB NeoPixel LED
  • 13 GPIO pins (11 breakout pads and two QT pads):
    • Four 12 bit ADCs (one more than Pico)
    • Two I2C ports (one on the QT connector, one on the breakout pads)
    • SPI and UART peripherals, in standard QT Py locations,
    • PWM outputs on every IO pin - for servos, LEDs, etc
    • There are 6 GPIO in consecutive order for PIO compatibility
  • 3.3V regulator with 600mA peak output
  • 12 MHz crystal
  • Both Reset button and Bootloader select buttons for quick restarts (no unplugging-replugging to relaunch code)
  • Really really small
