Description: 100% brand new and high quality Feature: This kit includes all the components and circuit boards, but does not include the power supply, antenna, cable, audio cable and coaxial cable. A 0.5W-7W FM transmitter without any debugging. Need you're a novice or a veteran, as long as you will welding, you can 100% successful DIY a high-quality FM transmitter. Mainly consists of various series microcontroller and a dot matrix LCD display screen and a keyboard. DSP + PLL technology, make the frequency more stable, the frequency does not change with the environment and produce frequency drift. No need any adjustment, bring the fun of DIY to beginners. The frequency can be continuous adjustment within the specified scope. With microphone input interface, and can through digital potentiometer to control the volume of the microphone. Audio input by digital potentiometer which can adjust the volume. Power can be between 0.5 W and 7 W maximum power continuous adjustment. The power output net-work for harmonic suppression is very good, make the output spectrum is more clean. Set the frequency and volume of power lost protection, the next boot does not need to set up again!

FM Transmitter Module V2.0 Digital FM Radio Module For Arduino Microphone Audio Description : Ever thinking about set up a music radio station yourself I think it would be great if you could build a music station and share your music with others. Pretty cool, right? This module could modulate your voice on the FM radio wave. And anyone who has a radio device could receive it. We build everything on this module, which makes it very easy to build a tiny radio station. We also reate library for Arduino to work with this module. We make everything easy for you. Feature : 1) I2C interface 5V TTL compatible 2) for Arduino plug and play 3) Onboard MIC 4) VCC Input: 3.0V ~ 5.0V you could wire them in the following way : for Arduino connect with FM Module as below : GND connect with GND 5V connect with VCC SDA connect with SDA SCL connect with SCL Then connect the antenna. Any metal line about 75cm can serves as an antenna. for Arduino Coding : We explain more about the code in the manual. Please refer to the manual for more information. Download the library and upload the example sketch to for Arduino. Package Included: 1 x FM Radio Transmitter Module V2.0 For Build Your Own Radio Station #FM #Transmitter #Module #V2.0 #Digital #FM #Radio #Module #For #Arduino #Microphone #

#0.1MHz-1.7GHz #TCXO #SDR #Receiver #R820T2 #USB #Tuner #ADSB #UHF #VHF #HF #FM #Full #Band 100% brand new and high quality Feature: The SDR is an extremely cheap software defined radio which is based on DVB-T TV USB receiver dongles that have the RTL2832U chip in them. It was discovered by hardware hacker Eric Fry, Linux driver developer Antti Palosaari and the Osmocom team who were developing their own SDR that the RTL2832U chip had a mode which enabled SDR. Today, by using custom software drivers, a commonly used cheap RTL2832U can then be turned into a sophisticated SDR with features that would have until recently cost in the hundreds to thousands of dollars. Of course, the performance of these dongles will not match a dedicated SDR, but they perform extremely well for the price, and almost all hobbyist projects that can be done with expensive radios or SDRs can also be done with the sdr. A wideband SDR opens up many interesting possible projects and avenues to explore. Some applications of the SDR include the following, some of which will be discussed in more depth in the project tutorials chapter. Fully assembled and ready to use Uses RTL2832U+R820T2 chip set. [the R820T2 tuner has slightly better sensitivity than the R820T and also works better at frequencies around 1.5 GHz. 100% compatible with software for the older R820T.] 100KHz to 1766MHz, operating frequency 1 PPM temperature compensated oscillator (TCXO) [Accurate tuning and almost zero temperature drift (2 PPM initial offset, 1 PPM temperature drift)] Covers all HF amateur bands Covers VHF & UHF bands from 24-1766MHz Up to 3.2 M Sample rate. (~2.8 MHz stable) Receiver modes AM, NFM, FM, DSB, USB, LSB and CW HF Shortwave Q branch direct sampling Note: depends upon the SDR software used with the receiver 8-bit ADC giving ~50 dB dynamic range 50 Ohm input impedance SMA golden antenna connectors It is also more durable and has lower insertion losses. Aluminum enclosure screened panels Independent antenna inputs for Shortwave and VHF USB computer connection ( mini usb) Powered by common USB All specifications subject to change without notice Specification: Material: Plastic and Metal Length: approx.92mm/3.15x3.62in Color: As pictures shown Quantity: 1 Set Note: Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
