B there are typically two options for powering the boards both consisting of sharing a power source The first is to let the external MCU board draw power from the SmartRF TrxEB the second is to power the SmartRF TrxEB from an external power source It is in both cases important that the voltage levels on shared signals are the same 7 2 1 Power external MCU from SmartRF TrxEB Power the external MCU board by connecting it to PWR and GND SmartRF TrxEB shown in Figure 21 Fn O O O O jO 1 Figure 21 Power external MCU board by connecting it to PWR GND 7 2 2 Power SmartRF TrxEB from external power source Connect the power from the external power source to the external power source connector on SmartRF TrxEB and set the power source selection jumpers accordingly Please see section 6 3 3 for a detailed description on how to power the SmartRF TrxEB from an external power source NOTE When powering the SmartRF TrxEB from an external power source the TrxEB main power switch must be in on position for the EB to be powered up Page 28 44 TEXAS 5 02944 INSTRUMENTS WRU294 7 3 Connect signals 7 3 1 Common signals Table 12 shows the common signals needed to communicate with transceivers on a mounted EM board Figure 22 shows where the signals listed Table 12 and
