Green rectangular Feather RP2040 board with USB-C connector and NeoPixel LED

Adafruit

Adafruit Feather RP2040 engineering development tool

SKU CH-2JE3-352C6

Microcontroller board with dual-core RP2040, 264 KB RAM, 8 MB flash, USB-C bootloader, 200 mA LiPo charger and NeoPixel indicator

  • Product typePrototyping Products
  • Dual-core RP2040 at ~125 MHz delivers fast 32-bit performance
  • 8 MB SPI flash stores CircuitPython and MicroPython code directly

  • 12 MHz crystal ensures accurate timing for real-time tasks
  • USB Type C gives access to ROM bootloader and serial debugging

Feather RP2040 development board

The Feather RP2040 is a compact prototyping platform built around the RP2040 32-bit Cortex M0+ dual core running at ~125 MHz with 264 KB RAM. It targets engineers, students and hobbyists who need a ready-to-program microcontroller board for embedded projects, sensor integration or CircuitPython experimentation.

8 MB SPI flash storage

The single specification that decides fit is the 8 MB SPI flash chip, which holds firmware, libraries and CircuitPython or MicroPython scripts without requiring external EEPROM. Projects that demand larger onboard storage or a different memory interface will need another board.

USB-C power and lipoly charging

A USB Type C connector supplies 3.3 V logic power, exposes the ROM UF2 bootloader and provides a serial debug port. The built-in 200 mA+ lipoly charger with status LED enables battery-powered operation, while the RGB NeoPixel and pin 13 red LED give immediate visual feedback during development.

Questions about this item

How fast does the RP2040 dual-core processor run when the board is powered at 3.3 V?

The RP2040 Cortex-M0+ dual core runs at approximately 125 MHz at 3.3 V logic and power, with 264 KB of RAM available for your program and data.

What does the USB Type C connector allow me to do with the built-in bootloader?

The USB Type C connector gives access to the permanent ROM UF2 bootloader so the board appears as a USB disk drive; hold the BOOTSEL button while plugging in, then drag firmware files onto it.

What battery connector and charging current does the on-board lipoly charger support?

The built-in charger delivers 200 mA or more to a standard lipoly pack and includes a charging-status LED; no EEPROM is fitted, so persistent settings must use the 8 MB SPI flash.
