Image of Board

The SparkFun Thing Plus - RP2040 is a low-cost, high performance board with flexible digital interfaces featuring the Raspberry Pi Foundation’s RP2040 microcontroller. Besides the Thing Plus or Feather footprint (with 18 GPIO pins), the board also includes an SD card slot, 16MB (128Mbit) flash memory, a JST single cell battery connector (with a charging circuit and fuel gauge sensor), an addressable WS2812 RGB LED, JTAG PTH pins, four (4-40 screw) mounting holes, and our signature Qwiic connector.

The RP2040 contains two ARM Cortex-M0+ processors (up to 133MHz) and features:

  • 264kB of embedded SRAM in six banks
  • 6 dedicated IO for SPI Flash (supporting XIP)
  • 30 multifunction GPIO:
    • Dedicated hardware for commonly used peripherals
    • Programmable IO for extended peripheral support
    • Four 12-bit ADC channels with internal temperature sensor (up to 0.5 MSa/s)
  • USB 1.1 Host/Device functionality

The RP2040 is supported with both C/C++ and MicroPython cross-platform development environments, including easy access to runtime debugging. It has UF2 boot and floating-point routines baked into the chip. While the chip has a large amount of internal RAM, the board includes an additional 16MB of external QSPI flash memory to store program code.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Past Releases

All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
