5W-7W FM Transmitter Kit Radio Station PLL Stereo Digital Frequency Kit Unassembled + LCD Display

5W-7W FM Transmitter Kit Radio Station PLL Stereo Digital Frequency Kit Unassembled + LCD Display

Description:
This kit includes all the components and circuit board, but does not include the power supply, antenna, cable, audio cable and coaxial cable.

A FM transmitter without any debugging. No matter you're a novice or a veteran, as long as you weld, you can 100% successfully DIY a high-quality FM transmitter.

Control panel components: mainly consists of 51 series microcontroller and a dot matrix LCD display screen and a keyboard.

Launch plate parts: digital FM radio chip launch sc3355 + 9018 + 2 + 2 + RD15HV sc2053 level 4 high frequency power amplifier and power regulation components.

Key Features of Transmitter Kit:
1. DSP + PLL technology make frequency more stable. Frequency does not change with the environment and produce frequency drift.
2. No any adjustment needed, bring the fun of DIY to beginners.
3. Frequency can be continuously adjusted within specified scope.
4. With microphone input interface, and can through digital potentiometer to control the volume of microphone.
5. Audio input by digital potentiometer which can adjust the volume.
6. Power can be adjusted in 5W-7W.
7. Power output network for harmonic suppression is very good, make the output spectrum is more clean
8. Set frequency and volume of power lost protection. No need to set up again for next boot.

Attention:
The kit is designed for beginners, basically no debugging, debugging difficulty is basically 0. As long as correct welding operation is followed, it can be carried out successfully. Whether you are a veteran or a novice, you can enjoy the fun of the least expensive FM transmitter DIY! As for SMD soldering, we don't have to worry too much. The capacitive resistor strip used in this kit is packaged in 0805, and the soldering board and the plug-in are the same.

A 50-ohm antenna must be used in this transmitter, and an antenna with a frequency of about 100m must not be used. Conductors, rod antennas, 2.4G antennas, and radio antennas should not be used.

Note:
- Assembling is needed. After welding can be used in accordance with the specifications set! Without any other debugging!
- This product requires customers to have certain basic knowledge and debugging experience.
