Description:
This is a set of 4 relays and associated circuitry to drive the relays with the low current of microcontrollers. Great for controlling 110V mains with a microcontroller. Board runs off 5V and requires up to 240mA when all 4 relays are activiated. Single sided PCB was designed in Eagle.

The default Arduino Fuse and Lockbit Settings are as follows:
Fuses
Extended:0xFD
High:0xD6
Low:0xFF
LockBits
Lockbit:0xCF
Sorry, no time to provide an expatiation of fuse bits now. After searching for ten minutes for a quick answer to program a stand alone Arduino capible board, had to look up the setting in the data sheet. Cant believe this hasn't been posted elsewhere, so I am making sure to capture it here.
