Figure 11 - DR-TRC105 Radio Board TX Power Adjustment
Two AA battery packs are supplied in the development kit to power the radio boards
when they are removed from the interface boards, as shown in Figure 12. Alternately, a
regulated power supply in the range of 2.7 to 3.6 volts can be used to power the radio
boards. Note - there are no voltage regulators on the radio boards. Applying a voltage
outside the specified power supply range can damage the boards. Do not attempt to
power a radio board directly through its battery connector using one of the 4.5 volt wall-
plug power supplies. The 4.5 volt power supplies are used to power the development kit
interface boards, which in turn provide regulated 3 volts to the radio boards. The AA
battery packs should only be used to power stand alone radio boards. They do not
provide enough voltage to reliably power the interface boards. Do not attempt to power
a radio board through its battery connector when it is plugged into an interface board.
