Adafruit Feather RP2040 Microcontroller Board

The Adafruit Feather RP2040 brings the power and versatility of the Raspberry Pi RP2040 chip into the popular Feather form factor, offering a compact and lightweight microcontroller board. Perfect for makers and developers, this board features a dual-core ARM Cortex M0+ processor running at 125 MHz, 264 KB RAM, and a large 8 MB SPI Flash for code and file storage.

This Feather board includes extensive GPIO with 21 pins supporting multiple protocols including I2C, SPI, UART, analog inputs (4 ADC channels), and PWM outputs. It also has a built-in 200mA+ LiPo charger, red LED on pin 13, an RGB NeoPixel for colorful status indication, and a STEMMA QT connector for easy I2C sensor and device connections.

Highlights include USB Type C connector for power and USB bootloader access, reset and bootloader buttons, support for PIO state machines to emulate advanced peripherals, and a right-angle tactile button for bootloader switch updated in 2022 for better usability with FeatherWings. This product ships assembled and tested, including headers for breadboarding.
