7 SmartRF05EB 

 
SmartRF05EB is the motherboard in the system, hosting all of the user interfaces and 
connections to external interfaces. 
 

 

Figure 14 - SmartRF05EB 

 
Figure 15 shows the main components of the board and outlines the main communication 
buses.

 

 

 

Figure 15 - SmartRF05EB architecture 

 
The main component on the board is the USB controller. It communicates with the PC via 
USB and translates requests from various PC tools (e.g. SmartRF Studio, SmartRF Flash 
Programmer) to actions on the board.
