About the Fpga extension PCB

Fpga extension is an open source RP2040/RP2350 PCB design by matgla, published on GitHub under the MIT license. It is a 6-layer board measuring 47.5 × 50 mm, with 120 components from 38 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the LFE5UM-85F-7BG381x, W25Q128JVS, W958D8NBYA, TLV75525PDBV and TLV75518PDBV. By type, the board carries 62 capacitors, 32 resistors, 9 ICs, 5 diodes, 4 connectors and 4 inductors.

It belongs with the usb & debug tools designs in this gallery.

From the project

Repository for MSPC hardware design

Hardware for MSPC: a small modular computer built from a mainboard and extension cards that plug into the MSPC bus. The mainboard runs yasos.

Every board is a KiCad project with its fabrication outputs next to it in outputs/.

- The projects are in KiCad 8 format. Newer KiCad versions upgrade them on the first save, and the result no longer opens in KiCad 8. Do such an upgrade as its own commit, with no design changes, so later diffs stay readable. - Schematic PDFs (outputs/schematic.pdf) are tracked, so the schematics can be read without KiCad. Gerbers and drill files are not: plot them…

The KiCad project lives in the matgla/mspc repository on GitHub; these links point at the commit this page was built from.

Fpga extension: common questions

What microcontroller does the Fpga extension use?

The Fpga extension is built around the RP2040, from the RP2040/RP2350 family.

How big is the Fpga extension PCB?

The Fpga extension measures 47.5 × 50 mm, has 6 copper layers and is 1.0524 mm thick.

How many components are on the Fpga extension?

120 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Fpga extension design files?

From the matgla/mspc 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 extension design in my own project?

Yes, under the terms of its MIT license, which matgla chose for the repository.

Can I test firmware for the Fpga extension 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.
