DSerial Edge
DSerial Edge is an I/O adapter for the NDS handheld console.
For DSerial² information go to DSerial2.

New Features
- Boots DS from microSD and microSDHC cards
- Complete Slot-1 solution
- 2 x UARTs
- 48MHz improved performance with C8051F34A microcontroller
- Remote debugging via GDB and devkitARM (to be released)
Note: RS232 level converter and accelerometer were removed, since they were under-used on DSerial2.

Troubleshooting
| Problem | Solution |
|---|---|
| Message "EDGE.DAT tidak menemukan!" appears | Insert a microSD card with EDGE.DAT. If it doesn't help, reseat the microSD card a few times to make sure the contact is good. |
| DSerial Edge is not detected by NDS or works intermittently | Clean the 17 contacts using a toothpick. Make sure that the toothpick is not sharp by cutting off its tip with a knife. There might be some dirt or residue due the manufacturing process. This is a standard maintenance procedure for a slot-based card. |
