Tools you need：

①Iron (30W) ②Solder wire ③Multimeter

⑤Wire cutters

1. Install the IC: IC.BH1417F corresponds to the silk screen on PCB Note that the welding pin must not be short circuited

R F - 0 3 P L L Stereo FM Transmitter kit instructions

Precautions:

④Twe ez er s

①Check part values & quantities against part list ②Always meter resistor values before soldering ③Understand all part polarities and orientations

2.Install the diode： 3. Installation resistance （bend is a zener diode 4.3V.Vertical Fit the 24 resistors on the PCB according is the variable capacitance diode FV1043） to the resistance values on the PCB ZD1 to 4.3V.VD1 to FV1043 Notice the direction of the diode
