Feather of the Day: Adafruit Feather RP2040 #RP2040 #Adafruit #Feather

The Adafruit Feather ecosystem is so rich with hardware diversity, we wanted to share them, one each day. Today is the Adafruit Feather RP2040!

When we saw the Raspberry Pi RP2040 chip, we thought “this chip is going to be awesome when we give it the Feather treatment” and so we did! This Feather features the RP2040, and all niceties you know and love about Feather.

Features:

  • 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
  • Tons of GPIO! 21 x GPIO pins with following capabilities:
    • Four 12-bit ADCs (one more than Pico)
    • Two I2C, Two SPI, and two UART peripherals, we label one for the ‘main’ interface in standard Feather locations
    • 16 x PWM outputs – for servos, LEDs, etc
    • The 8 digital ‘non-ADC/non-peripheral’ GPIO are consecutive for maximum PIO compatibility
  • Built-in 200mA+ lipoly charger with charging status indicator LED
  • Pin #13 red LED for general purpose blinking
  • RGB NeoPixel for full-color indication.
  • On-board STEMMA QT connector that lets you quickly connect any Qwiic, STEMMA QT or Grove I2C devices with no soldering!
  • Both Reset button and Bootloader select button for quick restarts (no unplugging-replugging to relaunch code)
  • Optional SWD debug port can be soldered in for debug access
  • Light as a (large?) feather – 5 grams
  • USB Type C connector lets you access built-in ROM USB bootloader and serial port debugging

You can program this Feather in Arduino or CircuitPython!

Because it’s part of our Feather ecosystem, you can take advantage of the 50+ Wings that we’ve designed to add all sorts of cool accessories. Plus that built in battery charging and monitoring you know and love is here.
