About the MDFPGA PCB

MDFPGA is an open source RP2040/RP2350 PCB design by aslak3, published on GitHub under the GPL-2.0 license. It is a 4-layer board measuring 99.1 × 73.7 mm, with 54 components from 28 distinct parts.

Its main chip is the SC0918, from the RP2040/RP2350 family. Other key parts include the DS3231M, ICE40UP5K-SG48ITR, AZ1117-1.2 and N25Q032A13ESC40F. By type, the board carries 17 capacitors, 13 resistors, 12 connectors, 4 ICs, 4 diodes and 1 module.

It belongs with the displays & leds and iot & wireless designs in this gallery.

From the project

A HUB75 display controller base board using a Pi Pico W and an iCE40UP5K

A schematic is included here, along with the KiCAD data files, which are in KiCAD 6 format.

The PCB is a 4 layer board easily built by any random PCB house.

This board is the hardware for my Matrix Display project, which is spread across three repos: this one, a repo holding the Pico W firmware, and an optional one that holds the HUB75 display controller, which is implemented in Verilog.

MDFPGA: common questions

What microcontroller does the MDFPGA use?

The MDFPGA is built around the SC0918, from the RP2040/RP2350 family.

How big is the MDFPGA PCB?

The MDFPGA measures 99.1 × 73.7 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MDFPGA?

54 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the MDFPGA design files?

From the aslak3/MDFPGA repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MDFPGA design in my own project?

Yes, under the terms of its GPL-2.0 license, which aslak3 chose for the repository.

Can I test firmware for the MDFPGA 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.
