Matrix
About the Matrix PCB
Matrix is an open source PCB design by adsehgal, published on GitHub. It is a 2-layer board measuring 65 × 45 mm, with 38 components from 4 distinct parts.
Other key parts include the Alchitry_Single. By type, the board carries 29 diodes, 8 resistors and 1 IC.
It belongs with the displays & leds designs in this gallery.
From the project
This repo collates my projects with the Alchitry AU FPGA
- Alchitry PCB Template : KiCad template for the FPGA board, provided by Alchitry
- I/O Shield with HDMI : I/O shield with a variety of peripherals including an LED matrix and HDMI. Uses original Alchitry connectors - Play Shield : Shield designed to work like a controller with two sets of directional arrow keys, 7-segment displays, LED array and HDMI.
The following is a list of boards I designed with a 1mm pitch connector instead of the original connectors that Alchitry uses: - Connector Adaptor : Adaptor board to convert the 0.5mm standard mezzanine connectors to 1mm pitch connectors -…

Matrix: common questions
How big is the Matrix PCB?
The Matrix measures 65 × 45 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Matrix?
38 components, from 4 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 Matrix design files?
From the adsehgal/Alchitry_AU 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 Matrix design in my own project?
The repository has no license, so all rights stay with adsehgal. Use it as a reference, and ask the author before reusing the design.
