The board contains an LCD, four pushbuttons, four LEDs and a buzzer, connected to a Silicon Labs 8051F930
MCU (U2, under the LCD). The MCU is also connected to an RF Pico Board connector pair (RFP1, RFP2). The
connection between the MCU and the EZRadio chip on the RF Pico Board is compatible with the RFStick. See
Table 1 for details. A Silicon Labs USB to C2 debug interface (U4) is also integrated on the board, so the board can
directly be connected via USB to the PC for downloading and debugging code on the U2 MCU.
2.2. RF Pico Board
Figure 2. RF Pico Board
The RF Pico Board is a radio module that contains an EZRadio IC, matching network and pcb antenna. The RF
output is selectable between the PCB antenna and a 50

SMA output connector via a 0

resistor. The boards
also have a factory loaded board identification memory (EBID) that contains data that describes the board
properties. Via the unified RF pico connector pair on the bottom side of the board, any RF pico board can be
connected to the LCD base board.
The example code runs on the C8051F930 MCU of the MSC-LCDBB930 LCD base board and controls the Si4012
on the RF Pico Board using the SMBus interface. The signals listed in Table 2 are connected:
