UG573: Si-MB4002A Wireless Pro Kit
Mainboard User's Guide
The Silicon Labs Pro Kit Mainboard is a carrier board for Silicon
Labs radio boards.
The mainboard provides all necessary tools for application development and debugging
of both the attached radio board as well as external hardware. Its features include an on-
board J-Link debugger, Packet Trace Interface (PTI) support, and a Virtual COM port.
The embedded Advanced Energy Monitor (AEM) can accurately measure the radio
board current consumption from 0.1 µA to 495 mA with a time resolution of 100 kSps. All
of these features can be accessed either through USB or Ethernet. The mainboard also
contains sensors and UI peripherals for easy demonstration of some of the capabilities of
an attached radio board.
