About the Fpga PCB

Fpga is an open source FPGA PCB design by linuxboot, published on GitHub under the GPL-3.0 license. It is a 6-layer board measuring 10 × 35 mm, with 37 components from 10 distinct parts.

Its main chip is the ICE40UP5K-UWG30ITR, from the FPGA family. Other key parts include the TPS7A2012PDQNR, AT25DF041B-UUN-T and RV-3028-C8. By type, the board carries 25 test points, 4 ICs, 4 capacitors, 3 resistors and 1 connector.

adaptersoldered`: KiCAD files for the soldered Flashkeeper chip adapter

adaptersoldered`: KiCAD files for the soldered Flashkeeper chip adapter

dummyboard`: Rigid PCB with multiple flash package footprints and connectors for testing and development

spispyboard: FPGA-SoM-based board to run spispy` during development

singlestencil`: Project containing all PCBs in a single file. Intended to export a single paste-layer Gerber so that all Flashkeeper boards can be made using different parts of a single solder paste stencil.

Fpga: common questions

What microcontroller does the Fpga use?

The Fpga is built around the ICE40UP5K-UWG30ITR, from the FPGA family.

How big is the Fpga PCB?

The Fpga measures 10 × 35 mm, has 6 copper layers and is 0.8 mm thick.

How many components are on the Fpga?

37 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Fpga design files?

From the linuxboot/flashkeeper repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Fpga design in my own project?

Yes, under the terms of its GPL-3.0 license, which linuxboot chose for the repository.

Can I test firmware for the Fpga without the hardware?

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