Thanks to the original author Gekkio for the open-source schematic: gb-schematics.
Update Log
2024-10-15: VDRV3 was missing a circuit, now complete. The circuit is located between pin 4 of U4 and VDRV3. For those who have already boarded and moved the board for troubleshooting, please run a jumper wire from pin 4 to the VDRV3 test point; it's very close.
2024-10-16: v1.1 verified and working normally.
The initial motivation for drawing this version was that I bought a refurbished GBASP with jumper wires, which annoyed me. So, on a whim, I searched GitHub extensively, but couldn't find any ready-made PCBs or gerbers, only schematics.
After importing it into LCSC EDA, I found that even the packages were missing. Faced with hundreds of fatal errors, I had to painstakingly complete the packages one by one. It took several months to reach this level.
The replication accuracy is only about 80%. Many silkscreens and fonts are not completely identical; they are slightly thinner than the original, and the large areas of white highlights around the buttons are not addressed.
I don't think this is a project for sale, so there's no need for a complete replica. Otherwise, it would be easier to just buy a 1:1 replica from Xianyu (a second-hand marketplace).
The main purpose of this project is to help those who want to repair things but don't have a component diagram, providing a repair reference.
Those who feel confident in their DIY skills can also try to reassemble the board themselves.
Regarding the BOM, the resistors and capacitors are corresponding. The transistors and diodes can theoretically be used directly. Other chips require reassembly.
Regarding the original console:
Let me promote our retro game console DIY exchange group: 771688226 (QQ group).
Our group currently has open-source projects including the GBA flashcart Chisflah ferroelectric version and the Chisflash SRAM version.
More replica projects will be open-sourced in the future, so stay tuned!
Regarding open-source emulators:
GBA-style open-source handheld console: FunKey A32G.
FunKey handheld console building and discussion group: Experts in the group help answer building questions, and there are various FunKey handheld console building materials.
