4.1. The Wireless Motherboard
Figure 2. Wireless Motherboard
The wireless motherboard contains four pushbuttons, four LEDs, and a buzzer as simple user interfaces. A
graphical LCD displays menu items for range testing purposes and a potentiometer demonstrates analog
capabilities of the MCU. A switch supports the power options of the MCU's built-in dc/dc converter. Using the
current measurement jumpers, current consumption can be measured separately either for the MCU, the radio, or
the peripherals. The motherboard contains test pins for all I/O pins of the MCU and for all digital pins of the radio. In
addition, there are SMA connectors for the GPIOs of the radio for test equipment connection. A USB
communication interface as well as a built-in Silicon Labs USB-to-C2 debug adapter are integrated onto the board
so that the wireless motherboard (WMB) can be directly connected via USB to the PC for downloading and
debugging code on the MCU.
An interface connection towards sensor modules can also be found. The MCU is also connected to the RF pico
board through a connector pair.
