ECHOA:

just replaced mine with a 5v 3a supply and the plug I used was a 1.7mm X 4mm.? I wouldn't go past the 3amp. Couldn't find the usb type had to buy the one piece molded unit.

The Firefly is internally protected at the dc plug with a 3 Amp fusible link. So if pull over 3 amps on the board you will be learning how to solder a new power plug on the board. Look at the schematics third page power supply upper right hand corner.

That was the size of the plug I ordered from EBAY with my new power supply and it worked perfectly.? Are you sure you need this or are you ordering your first one.? As I have mentioned I am not a normal user of the power for a normal user and the 2.5 amp if you have one should be fine.? Me I power everything from the board and with my pins in and pins out at times looks like noodle soup.
