RED4 User’s Manuals - Preliminary Version 2 Operation Method Figure 2 Application Circuit 2.1 Power Supply DC power to operate RED4 is separated by 2 kinds. VCC36 is to supply for PR9200 which power range is 3.3 to 3.6 volts, VCC36P is to supply for power amp which power range is 3.3 to 4.2 volts. Total current consumption of RED4 is typically 450mA at 25dBm output power. 2.2 UART The serial interface is assigned with two wires.
