Welcome to the gbaHD-Shield Wiki!

What is the gbaHD-Shield?

---

The gbaHD-Shield is a all-in-one solution to connect your GBA (OGBA) and your GBA-SP to the Spartan-Edge Board to use it with the gbaHD-Project. The gbaHD-Shield offers the needed flexconnectors for the display pins and a OGBA / GBA-SP specific hookup board for the controls.

There is also an newly designed Flexcable which replaces the modelspecific hookup boards with an flexcable, that can be soldered directly onto the GBA / SPs CPU

Heart of the gbaHD-Shield is it's ATMEGA328P / ATMEGA168p which grabs the buttonpresses from the 7-Pin SNES-Style connector and sends them through shift registers to the OGBA / GBA-SP Mainboard.

It has the following features.

• Connects via female headers to the Edge board (shield)
• Has a FFC 40 pin connector for OGBA LCD connector. Need Type-B Cable (Reverse) vvv=======^^^
• Has a FFC 32 pin connector for OGBA LCD connector. Need Type-B Cable (Reverse) vvv=======^^^
• Has a FFC 34 pin connector for GBA-SP LCD connector. Need Type-A Cable (Direct) vvv=======vvv

• Has a ATMEGA328p / ATMEGA168p / ATMEGA88p for using a SNES connector to control the GBA.
• Has a high-side switch for GBA power controls (IGR).
• Optional Flex-Cable to solder on the the CPU of the GBA and the GBASP
• Unused ATMEGA-Pins are broken out as testpoints on the top and bottom side for future features.
