The data sheet shows the peak power consumption for the Xbee-Pro to be 250 mA although 340 mA for the RPSMA connector version. Why does the RPSMA version require more power if the antenna is 50 ohms ?
Looking at the schematic for the XBIB-U-DEV, page 4, shows a switching regulator, U4. What is the expected voltage, Vcc, on the schematic ?
