5W-7W FM Transmitter DIY Radio Station PLL Stereo Digital Frequency Kit Assembled + 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.
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.
