It belongs with the dev boards & breakouts designs in this gallery.

From the project

Home of everything RPGA! From schematics and board files to buildable examples!

Welcome to the RPGA Feather GitHub page. This page is designed to be a single source of truth for this board, including board files like schematics, production files, BOM, and more. In addition to that, there are also a handful of examples available to build with just a little effort specifically for the RPGA Feather.

What is the RPGA Feather? RPGA Feather is a development board which provides the ease of use of the RP2040 from Raspberry Pi with the wide open source support of the iCE40 FPGA line. RPGA Feather combines the RP2040 with an iCE5LP4K FPGA from Lattice Semiconductor which has…

RPGA-Feather: common questions

What microcontroller does the RPGA-Feather use?

The RPGA-Feather is built around the RP2040_M0+, from the RP2040/RP2350 family.

How big is the RPGA-Feather PCB?

The RPGA-Feather measures 50.8 × 22.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RPGA-Feather?

67 components, from 32 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the RPGA-Feather design files?

From the Oak-Development-Technologies/RPGA-Feather repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the RPGA-Feather design in my own project?

Yes, under the terms of its MIT license, which Oak-Development-Technologies chose for the repository.

Can I test firmware for the RPGA-Feather without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
