The Handheld TFTP Server project combines the functionality of Ethernet and a TFTP Server with the convenience of USB in a small form-factor. The project is sponsored by GE Microwave Data Systems in Rochester, NY as a device for deploying software updates to Microwave radios which utilize TFTP for firmware programming
Connecting the board to a computer through a USB cable presents an interface identical to one you'd see with a common commercial USB "Thumb drive" or "Flash Drive". When the device is connected to a GE radio with an Ethernet cable, standard TFTP commands can be issued to get files stored on the device. An Orange LED will display the status of the file transfer, while a Green LED will light up when the file is successfully transfered. The board will be powered by four AA batteries in a battery pack.
