This kits is bulk package, need buyers to welding (relatively difficult welding chip we have welding welding) without having to worry about, without any test. After welding can be used in accordance with the specifications set! Without any other debugging! While all of the materials for electronic information, buyers need to leave email after purchase we unified the hair! Or online to send!
This kit includes all the components and circuit boards, but does not include the power supply, antenna, cable, audio cable and coaxial cable.
A 7W FM transmitter without any debugging. Need you’re a novice or a veteran, as long as you will welding, you can successful 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.
Transmitter kits key features:
1, DSP + PLL technology, make the frequency more stable, the frequency does not change with the environment and produce frequency drift.
2, no need any adjustment, bring the fun of DIY to beginners.
3, the frequency can be continuous adjustment within the specified scope.
4, with microphone input interface, and can through digital potentiometer to control the volume of the microphone.
5, audio input by digital potentiometer which can adjust the volume.
6, power can be between 0.1 W and 7 W maximum power continuous adjustment.
7, the power output network for harmonic suppression is very good, make the output spectrum is more clean
8, set the frequency and volume of power lost protection, the next boot does not need to set up again!
Kits main parameters:
1, the input voltage: dc 12 v
About 2, input current 3.0 A
3, the audio signal: the maximum input Vpp is less than 1 v.
4, microphone types: cylinder microphone or microphones!!!!
5, the output power: 0.5 W – 7 W continuous adjustable!
6, the output impedance: 50 Ω
7, working frequency: 76 m – 108 MHZ
Step: 8, frequency of 0.1 MHz
9, the distortion degree: 0.03% ~ 0.1%
A, the board size: fire board: 100 x 60 mm (excluding fin)
Control panel: 58 x 36 mm
B, the launch distance: more than 8 km (premise is open field emission)
C, stereo separation degree: greater than 63 db
The suite is demanded by beginners special design, basic no debugging, debugging difficulty is basic for 0. as long as according to the correct welding operation can be successful. Whether you are veteran or a rookie, all can enjoy to spend the least cost FM launch DIY fun! As for patch welding, we don’t have to worry about too much, this suite USES capacitive resistor strips are 0805 encapsulation, welding board and plug-ins is the same,
Antenna must be used in this transmitter 50 ohms, frequency of about 100 m antenna, shall not be used conductor, rod antenna, 2.4 G antennas, radio antennas instead
