Absolute maximum battery voltage is 3.6V. USB or battery can be chosen with SW1. When switching to battery, the RS232 transceiver is disabled because of its high current consumption. When using battery, the current measurement should also be switched off to avoid excessive leakage current to the instrumentation amplifier U2. To minimize the leakage currents the display, accelerometer and the potentiometer can be turned off and disconnected from the module by SW2, SW5 and SW6. 5.2 USB The board operates as a bus powered USB device. 5.3 RS232 The board operates as a DTE (data terminal equipment). Because of high peak currents of the RS232 transceiver, RS232 can only be used when powering the board from USB. When switching to battery the RS232 transceiver is automatically disabled. RS232 can also be disabled and enabled by SW3. When the RS232 transceiver is disabled all of its outputs are set to high impedance state and UART can be used through the pin header. 5.4 Accelerometer and the Display The accelerometer and the display share the same SPI interface. The display is selected by taking the chip select signal low and the accelerometer is chosen by taking the chip select signal high. A charge pump generates 3.3V supply voltage for the display. 5.5 Programming Interface Programming interface is in J11. Bluegiga Technologies Oy Page 15 of 19 5.6 Pin Header and Buttons All the PIOs are available and permanently connected in the pin header J2. In order to use certain PIOs through the pin header, that particular PIO must be disconnected from the device to which it is connected so that it is not actively driven by two devices. Following table shows the PIO connections in the evaluation board.

When powering from a battery, the current consumption should be disconnected with SW12. The current consumption of BLE112 is measured over 3 ohm resistor using an instrumentation amplifier with a gain of 10. The instrumentation amplifier is powered from USB 5V line and the DC bias is from the 3V3 LDO. Because the amplifier is powered from the USB VBUS, it can't be used unless USB is connected. If USB is not connected then the instrumentation amplifier must be disconnected by SW12 to avoid excessive leakage current into the input of the amplifier. + A=10 3R - Ref 3V3 Figure 11: TX current measurement amplifier To measure the TX current consumption of the module, connect a coaxial cable to the BNC connector in the board and to an oscilloscope. Set the oscilloscope Coupling: DC Vertical scale 500 mV/DIV Horizontal scale: 200 s/DIV Level: 2.5 V Offset: -2.0 V Trigger: Normal, falling edge The instrumentation amplifier inverts the signal. The current consumption is calculated by I 3.3V Vo 30 The DC current consumption of the whole board can be measured by connecting a current meter to header J8 if powering from USB or J9 if powering from a battery.
