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)
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
