1. A selectively programmable radio frequency (“
- RF”
) remote access device, the remote access device comprising;
a logic board comprising a processor and at least one memory;
a set of user inputs;
a transceiver;
wherein the at least one memory comprises a first read-only memory comprising a plurality of firmware configurations for the logic board, and a second memory which comprises an active memory partition adapted to store an active firmware configuration;
wherein each firmware configuration in the plurality of firmware configurations comprises a set of properties for controlling the processor, the memory, and the transceiver;
wherein the active firmware configuration is read from the plurality of firmware configurations from the first read-only memory based on a user input from the set of user inputs and is written into the active memory partition of the second memory; and
wherein the logic board is automatically configured by the selected firmware configuration loaded into the active partition of the second memory to communicate with an external device via the transceiver.
