Image of Board

What better way to enjoy a Raspberry Pi RP2040 than to pair it with an iCE40 FPGA. iCE40 FPGA provide a small but capable accessory to your favorite project without the hassle of figuring out the wiring and which pins to hook up!

RPGA Feather comes equipped with the RP2040 and the iCE5LP4K fpga from Lattice Semiconductor which features 3520 LUTs, 80kb of BRAM, hardened I2C and SPI blocks (no wasted LUT for soft blocks), and a number of pins both hooked directly to the RP2040, as well as jumper blocks on the bottom to either connect up to 4 additional pins to the RP2040 or provide 4 IO for the fpga.


  • 2MB QSPI FLASH (w25q16)
  • LiPo Charging via MCP73831 1S LiPo Charger
  • Up to 12 direct pin connections to the RP2040 from the iCE5LP4K
  • USB 2.0 Type C Compatible connector
  • Cree RGB LED driven by FPGA
  • Compact and versatile Feather Form Factor
  • StemmaQT/QWIIC compatible JST connector

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. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Previous Versions of CircuitPython

All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.

Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
