Set 1: DIY kits
Set 2: Assembled , ready to use .
Description:
Now the transmitter to make a brief introduction:
◆ control panel components: mainly by M8 Series MCU and LCD display and keypad.
◆ transmitter board components: digital FM transmitter chip + 9018 + 2SC3355 + 2SC2851 + 2SC1971 four high frequency power amplification and power conditioning components.
◆ transmitter kit Main features:
1, DSP + PLL, the frequency is more stable, the frequency will not change with the environment to produce a frequency drift.
2, without any adjustment to bring the fun of DIY beginners.
3, the frequency can be continuously adjusted within a specified range.
4, with a microphone input and speaker volume can be controlled via digital potentiometer.
5, audio input volume can be adjusted via a digital potentiometer.
6, power can be adjusted continuously (non-linear) between the maximum power of 0.5W to 7W.
7, the power output is very good harmonic suppression network, the output spectrum cleaner
8, frequency and volume settings have power failure protection, you do not need to set the next boot!
