FM Transmitter Solution

Simple and easy to use FM audio transmitter, without making complicate protocol and using common used radio as the receiver to achieve a low cost audio wireless solution.

Application:
MP3 transmitter, car MP3 transmitter, PSP transmitter, wireless stereo microphone, wireless headphone etc.

Globaltec can offer two type of IC or complete solution up to module level.
For component level, we have two type. The first type can be used with MCU to form deluxe solution while the B type is the low cost version.

FM transmitter solution
Platform was built with various series of MCU which can quickly build application based on customer requirement.
Firmware has built with LCD MCU, touch sensor interface, EEPROM for memorial the favour channel.
With the established core, we can build to control different FM transmitter IC

Feature List:
1. 4 memories to store favour channel.
2. up and down key (Option with touch sensor interface).
3. LCD display.
4. Operating frequency display.
5. Auto detect eeprom failure.
