About the VGA SRAM SHIELD DB MULTIPLEX

VGA SRAM SHIELD DB MULTIPLEX is an open source AVR/Arduino PCB design by levvayner, published on GitHub. It is a 6-layer board measuring 99.5 × 53.5 mm, with 42 components from 30 distinct parts.

Its main chip is the Arduino_Due_Shield, from the AVR/Arduino family. Other key parts include the 74LS161, GAL22V10, 74HC245, 74LS32 and 74HC14. By type, the board carries 20 ICs, 12 resistors, 7 connectors, 1 module, 1 crystal and 1 capacitor.

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

From the project

If choosing the former, follow Atmel's instructions using the included .pld files. If chosing the latter, you can open the workspace and you will see both projects. You can build and deploy the projects right from Code!

If choosing the former, follow Atmel's instructions using the included .pld files. If chosing the latter, you can open the workspace and you will see both projects. You can build and deploy the projects right from Code!

You will need to download the Atmel Wincupl progam either way. If you chose to use VS code, you will also need to download and install minipro. More instructions about requirements can be found in the VS Cupl repo https://github.com/levvayner/ATF15xx-cupl

VGA SRAM SHIELD DB MULTIPLEX: common questions

What microcontroller does the VGA SRAM SHIELD DB MULTIPLEX use?

The VGA SRAM SHIELD DB MULTIPLEX is built around the Arduino_Due_Shield, from the AVR/Arduino family.

How big is the VGA SRAM SHIELD DB MULTIPLEX?

The VGA SRAM SHIELD DB MULTIPLEX measures 99.5 × 53.5 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the VGA SRAM SHIELD DB MULTIPLEX?

42 components, from 30 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 VGA SRAM SHIELD DB MULTIPLEX design files?

From the levvayner/VGA_PLD 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 VGA SRAM SHIELD DB MULTIPLEX design in my own project?

The repository has no license, so all rights stay with levvayner. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the VGA SRAM SHIELD DB MULTIPLEX without the hardware?

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