The schematic of an RF Pico Board can be found in the next chapter. The complete CAD design pack of each RF
pico board type is also available at www.silabs.com.
5.4. Setting up and Connecting the WMB to the PC
Steps for connecting the platform to the PC:
1. Connect an RF Pico Board to the WMB board through the CON1 and CON2 connectors.
2. Insert a UPPI-930-RF MCU pico board in the connectors J5, J6, J7, J8 on the WMB. The dotted corner of
the C8051F930 MCU has to point to the triangle symbol on the WMB.
3. Connect an antenna to the SMA connector on the RF Pico Board.
4. Select the desired power source with the SUPPLY SELECT switch.
5. Ensure that all the CURRENT MEASUREMENT jumpers are in place.
6. Connect the WMB board to a USB port of the PC.
7. Wait for Windows to install the driver of the debug interface if necessary.
