Default Firmware

All SBC66 Boards are programmed with default firmware at delivery. In addition, boards with a USB port also has a USB Bootloader programmed onto it. This is a small program that resides in the first couple of KBytes of program memory, and is activated at start up if the jumper is placed in the "F" position. It allows the firmware of the board to be updated via the Netcruzer USB Bootloader.
