The Wireless Motherboard Hardware Platform The wireless motherboard platform is a demo, evaluation, and development platform for EZRadioPRO radio ICs. It consists of a wireless motherboard and interchangeable MCU and RF pico boards. Figure 2. 8-Bit Wireless Motherboard Platform Rev. 0.4 7 EZRadio-DK User ’s Guide 5.1. The Wireless Motherboard MCU Pico Board RF Pico Board USB Communication and Debug Interface Current Measurement Pins External Power Supply Connection Radio Test Pins Sensor Module Connector Power Supply Switch Radio GPIO Connectors MCU DC/DC Converter Switch MCU Test Pins Potentiometer Push Buttons Reset Button Buzzer Figure 3. Wireless Motherboard The wireless motherboard contains four pushbuttons, four LEDs, and a buzzer, which function as simple user interfaces. A graphical LCD displays menu items for range testing purposes, and a potentiometer demonstrates the 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 connection of test equipment. 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. There is also an interface connection for sensor modules. The MCU is also connected to the RF pico board through a connector pair. 8 Rev. 0.4 EZRadio-DK User ’s Guide 5.2. Power Scheme The power source of the platform can be selected with the “SUPPLY SELECT” power supply selector switch on the WMB board. If this switch is in the “USB” position, supply voltage is provided by the PC that is connected to the “J16” mini USB connector. If this switch is in the “BAT” position, the supply voltage is provided by two AA batteries in the battery holder on the bottom side of the board. If the “SUPPLY SELECT” switch is in the “EXT” position, supply voltage is provided by an external power source through the “TP7” and “TP9” points. Using the “MCU dc/dc” switch, the internal dc/dc converter of the C88051F930 MCU on the MCU pico board can be activated if the connected pico board supports this function. If the switch is in the “OFF” position, the MCU’s dc/ dc converter is inactive, and the supply voltage is only determined by the state of the “SUPPLY SELECT” switch. Positioning the switch to either “LDO (1.25 V)” or “1 CELL” position will turn on the MCU’s dc/dc converter by connecting 1.25–1.5 V supply voltage to the VBAT pin and removing external power from the VDC pin. The MCU will provide 1.9 V in the default setting on its VDC pin to all the other connected loads. Since this current is limited, it may be necessary to disconnect or disable some loading part of the board. For further details, see the MCU data sheet and the board schematic. The board schematic can be found in the EZRadioPRO Development Kit User's Guide. A complete CAD design pack of the board is also available at www.silabs.com. 5.3. RF Pico Board Figure 4. RF Pico Board Top Side The RF pico board is a radio module that contains an EZRadio radio IC, matching network, and an SMA connector on the top side. These components (apart from the antenna connector) are covered by a metal shield for noise reduction. The digital signals of the radio (SCLK, SDI, SDO, NSEL, SCL, SDA, VDD and GND) can be accessed on test points at the edge of the board. The boards also have a factory-loaded board identification memory (EBID) on the bottom side that contains data describing the board properties. Any RF Pico board can be connected to the WMB via the unified RF Pico connector-pair on the bottom side of the board. Table 4 lists the connections between the MCU and the radio or other peripherals. Some GPIOs of the MCU has dual function. Primary functions are factory connected on the WMB. Secondary functions can be connected by desoldering a 0 resistor that connects the primary function and soldering it into the proper position to connect the secondary function. Secondary connections are listed in parenthesis in Table 4. Rev. 0.4 9 EZRadio-DK User ’s Guide Table 4.
