There is a pad in the corner on the underside which if too close to the fuse pad may touch, short, and blow the fuse. If possible, test prior to assembling. Note: Be careful removing, it's very easy to strip the pads from the PCB.
This product would be ideal for individuals looking to upgrade their Game Boy Advance (GBA) or Micro Game Boy Advance (MGB) or AdvanceGB handheld gaming consoles with an upgraded audio socket.
