Mini Stereo Digital FM Radio Receiver Module 76MHz-108MHz SUPPORT CUSTOMIZE OEM

    This module for miniature patch FM receiving modules, design USES digital IC component, frequency very stable, high precision, to avoid the use of division of the element has run frequency problem. User use also is very convenient, and need not welding antenna, as long as give module can be realized after power up signals, through stereo headset mouth connect the headset or active power amplifier achieve voice played.

Hardware Description

      Receive frequency: 76 MHz to 108 MHz, frequency covers the whole FM frequency band;
      Module output by a user voice buttons Settings, and can real-time storage, after power off and on again electric keep the last time when using frequency;
      Users can also specify receive frequency, we will fix it again shipment.
      Antenna for them, to drag a headset line a long antenna troubles.
      Sound quality pure, if equipped with a pair of good headphones, let you experience the enjoyment of class!!!!!

Description

GPS is electronic fans very keen on a topic of GPS, in the civil and military, navigation, space is widely used in the field. Many mountaineering outdoor enthusiasts also are equipped with GPS device, used for the wild navigation. GPS module price more and more accessible, and let more and more products into the GPS module, electronic lovers GPS module also study is no longer a luxury.

At the same time to adapt to different power supply system, we use the 3.3 V and 5 V two power supply mode.

In serial ports, provide TTL level and 232 level, the user to choose according to need different configuration.

Hardware Description

1, on-board quality power switch, convenient program debugging and switch machine operation.

2, power source design using large current special power IC module 29302, to ensure that the power supply circuit stable power supply. Now in the market of some cheap development board we see many is directly use the LM7805, for 5 V output voltage is very close to the module of the upper limit of critical point, so long time work, poor stability, is more dangerous, the 7805 biggest can output current is 1.5 A, and we use the 29302 the maximum output current up to 3 A, want to know when the GSM, sometimes the current moment is very large, especially in some signal not place, in order to search the network signals, module will promote the transmission power, then the current consumption is very big, the power circuit is bad, stability of words, will reflect the problem. We had some development board to market a sampling test, the fact found that many board in some signal is bad, are not normal communication and work, we test did corresponding shielding control.

3, on-board hardware resources interface rich:

-provides NOKIA5110 LCD interface, the screen is very extensive use, also very cheap.

Buzzer circuit: 5 V active buzzer drive, can happen prompt, the convenient user of debugging and do remind function setting, compact and practical function.

The temperature sensor DS18B20 interface: 1 line in the digital temperature sensor interface, occupy a single chip I/O mouth, can obtain real-time temperature, it is stable and reliable.

4 * 4 matrix keyboard: users can in a program in custom keys function, achieve control buttons. Used to do a cell phone dialing system more than sufficient.

1 road relay for users to do: interface text message or telephone realize relay control, relay control load in the 220 V cases, 3 A of current.

4, 4 road LED indicator lights: the user can state by light and put out four road LED tube, convenient program commissioning work.

5, three kinds of communication way jump line: PC and MC323 CDMA module communication;

PC and single-chip microcomputer communication: board of STC89C52 single-chip microcomputer chip can download a program through a serial port complete the ISP, without additional programmer.

EM310 module microcontroller and communication.

6, open microcontroller I/O extension mouth: SCM 40 pins all leave, the mouth for users to expand the use, the microcontroller both sides each put 20 holes, all with chip pins directly connected.

7, on-board headset port: we design the module in board the microphone interface circuit, increased the headphone jacks, the user as long as by ordinary computer headset can realize voice call, hey hey, the sound quality is good oh (^_^)!!!!!

8, STC89Cxx, the highest frequency of 90 MHz, within 4 K of FLASH memory, the program more than 8 K or so in EEROM, 512 of B-1208 B within 36 of RAM, IO mouth.

9, 1 LED indicator light: a power instructions.

10, ISP interface (used for program download, serial ports surveillance).

11 and RS232 interface ISP; Support a serial port debug.

12, 9 v dc power input: take the power indicator.

    Super miniature efficient FM radio stereo launch module according to several years of user feedback and the practical experience of improved the latest FM launch module products. We by the circuit is stable and reliable quality of digital IC, patch components, frequency very stable, high precision, to avoid the use of division of the element has run frequency to ensure that the product, more consistency and reliability, and before shipping products are after two rf spectrum meter test and actual listening test, everyone please be sure to trust to purchase to ensure that each of us is before shipping product!!!!! 

Hardware Description

    1, working voltage 2.4-3.3 V, working current mA@3.3V, 25, 40 mA@2.4V

    2, launch frequency range 67 MHZ, 128 MHZ, launch frequency covers the whole FM frequencies, through the key regulation.

    3, launch frequency interval 0.5 MHz, can actually reach 0.1 Hz ac, but considering the receiving device, we set to 0.5 MHz, such as a need to amend stepping value, can contact us.

    4, volume is small and exquisite, is equal to half the smaller chewing gum.

    5, use a wire as the antenna, the length of the antenna according to actual listening environment can be appropriately increase or decrease forehead!!!!!

    6, and the use of digital regulation method, frequency cycle regulation, need not worry frequency range beyond receive.

    7, launch piece and FM radio in testing and using FM, no distance limit, far to 50 meters, nearly to a few centimeters, won’t because the distance from screaming. Nearly cry

    8, launch frequency stability accurate, automatic display can capture a, use more convenient.

    9, launch for a few centimeters distance to 50 meters, commonly keep out words in 30 meters or so. And the environment around antenna also has much higher height, launch, steel and concrete structures around the less effect and the launch distance. Of course, the best open place!!!!!
