Universal CLA/FM Transmitter F8V7105 Description 1/2 F8V7105 is a digital tuning FM transmitter with CLA and USB powered unit, this system consists of a FM transmitter, a car adapter and a USB connector, a MCU controller, a LCD display, an EEPROM programmer, as well as an audio detector, In addition to two press keys which are used to turn the proper FM frequency. Transmitter The transmitter is a FM stereo transmitting configuration, which radiates FM wave on the air by modulating the carrier signal with a composite signal. Transmission frequency is set from 88.1 to 107.9MHz. MCU controller This MCU controller (Samsung S3P9234) is used to control the systems radiating frequency by exchange data with the FM transmitter, in which we can press down and up button to select the transmission frequency for broadcast. two memory buttons can be used to store the frequency through the EEPROM. Press and hold the button for 2 seconds, then the icon will flash to indicate the desired frequency is stored. In the operation mode, press M1 or M2 button retrieve the memorized frequency. In addition, LCD display The LCD display is used to indicate the transmission frequency, so users can set the same channel for their car radio conveniently. Universal CLA/FM Transmitter Audio detector 2/2 Through the MCU controller, the unit will turn on when it detects an audio signal automatically. Power supply This product can be powered by an DC to DC regulator within the cigarette lighter adapter. The DC regulator LM2596S-5.0 is a switch regulator, which transforms input DC into 5VDC as the whole systems power. Control button There are three function press buttons. One is up button for turning up the frequency, another is down button for turning down the frequency, and the other two buttons are for memories. Users employ those keys to manipulate easily. In addition to the above function, we can press and hold both up and down buttons simultaneously for about two seconds turn on the unit. To turn off the unit, press and hold both buttons simultaneously again for two seconds or so. At operation mode, press M1 or M2 button will toggle the memory slots to retrieve the memorized frequency. Moreover, when there is no key press after ten seconds the unit will return from memory mode back to operation mode. Auto Power on & Auto Power off If there is no audio input audio signal for 1 minute, the unit will power off automatically to conserve the power while the unit detects the input audio signal again, it will power in again automatically.
