About the Dmgplus PCB

Dmgplus is an open source FPGA PCB design by Spritetm, published on GitHub. It is a 2-layer board measuring 78.5 × 80 mm, with 108 components from 35 distinct parts.

Its main chip is the iCE40-HX4K-TQ144, from the FPGA family. Other key parts include the XC6206P122, NS8002, XC6206P252, MCP6021 and GB_LCD_FLAT. By type, the board carries 45 capacitors, 27 resistors, 14 ICs, 8 connectors, 7 diodes and 2 switches.

It belongs with the retro computing designs in this gallery.

From the project

DMGPlus, upgraded internals for the original GameBoy

These are various files for the DMGPlus project. Note that I did this over the time span of about three years, so there's no plug-and-play recipe to build your own available; I'd need to reverse my own work to provide that. As such, these files are only provided as a reference, to plunder if you want to build something similar. For more information about the DMGPlus project, refer to https://spritesmods.com/?art=dmgplus

Dmgplus: common questions

What microcontroller does the Dmgplus use?

The Dmgplus is built around the iCE40-HX4K-TQ144, from the FPGA family.

How big is the Dmgplus PCB?

The Dmgplus measures 78.5 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dmgplus?

108 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dmgplus design files?

From the Spritetm/dmgplus repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Dmgplus design in my own project?

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

Can I test firmware for the Dmgplus 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.
