Super DMG CPU
About the Super DMG CPU PCB
Super DMG CPU is an open source PCB design by awhit003, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 83 × 78.5 mm, with 42 components from 21 distinct parts.
Other key parts include the LPW5209B5F-21. By type, the board carries 21 capacitors, 11 resistors, 1 IC, 1 crystal, 1 connector and 1 switch.
It belongs with the audio and power & battery designs in this gallery.
From the project
Super DMG CPU works with both IPS and DOT MATRIX LCD boards.
Super DMG CPU works with both IPS and DOT MATRIX LCD boards.
The schematic is largely based on the work done by bit 9.
I used Gekkio KiCAD libs for a few symbols (cpu, ram, cart connector, link port). The specialized footprints were traced by me using fusion 360, using these scans by bit 9 as a reference.
v1.8 and below have an error with the Link Port, where the footprint was flipped (sigh). If you have a v1.8 or below please don't use the link port, as it might damage the other Game Boy! This was fixed in later versions.
