Adafruit Feather RP2040 - Qwiic

Love the Adafruit Feather format? Interested in using Raspberry Pi silicon? Then you’re in luck! With the Adafruit Feather RP2040, you’ll be creating new IoT projects in no time. The super-compact Adafruit Feather RP2040 features 8-MB flash, USB-C, 21 GPIO pins, a built-in battery charger, and STEMMA QT. Quickly connect sensors and start innovating.

Inside the RP2040 is a 'permanent ROM' USB UF2 bootloader. What that means is when you want to program new firmware, you can hold down the BOOTSEL button while plugging it into USB (or pulling down the RUN/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto. Folks who have been using Adafruit products will find this very familiar – Adafruit uses the technique on all their native-USB boards. Just note you don't double-click reset, instead hold down BOOTSEL during boot to enter the bootloader!

The RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD21). Since it is an M0 chip, it does not have a floating point unit, or DSP hardware support – so if you're doing something with heavy floating-point math, it will be done in software and thus not as fast as an M4. For many other computational tasks, you'll get close-to-M4 speeds!

For peripherals, there are two I²C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO – check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout).

Quick Spec

  • RP2040 32-bit Cortex M0+ dual core running at ~125 MHz @ 3.3 V 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, one is labeled 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
