Introduction:

• The product is about the TEA5767 87.5.0MHz-108.0MHz Wireless FM Radio Receiver DIY Kit.
• It has a red 4Bit segment display screen which can clearly display the receiving frequency.
• It is a very interesting DIY electronic product which enables users to understand the circuit more clearly and learn soldering skills.

Feature:

• 87.5Hz-108MHz Frequency: It adopts the universal FM reception frequency with 0.1MHz accuracy. Directly set and change the receiving frequency by two buttons.
• 4ohm 3W Speaker: Built-in power amplifier that can drive mono 4ohm 3W speakers directly and the sound is very clear.User also can connect headset. Adjust the volume by potentiometer
• Power Saving Mode: 0.56in 4Bit Digital Display Tube Screen can display and query the current FM frequency at any time. Automatically turn off the display after 5s without any operate to energy conservation.
• Power-off memory FM station: continue to play the FM radio station before the power turn OFF, when the power is turned on again.
• DIY Electronic Soldering Kits: It’s a DIY kit which comes with various components. User need to install each component by hand. It not only can exercise and improve soldering skills, but also increase the interest in electronic technology. Great for electronics hobbyists, beginners, school and home education.

Parameter:

• Work Voltage:DC 4.5V~5.5V
• Output impedance:4ohm
• Output power:3W
• Output channel:Mono
• Audio source:FM
• Output type: Speaker or AUX
• Size(Installed):89x81x47mm

Use Methods:

• Press KG switch to turn ON/OFF work power.
• Press K1 button to increase receiving frequency.
• Press K2 button to decrease receiving frequency.
• Rotate potentiometer to adjust the volume.
• Display screen automatically turns off to save power if there is no any operate within 5second. That is to say, after the screen is displayed for 5 seconds, it will automatically turn off. Press any buttons to wake up the display. Note: It is not only used to save power, but also to avoid signal interference from digital tube displays.

Note:

• The frequency can be adjusted continuously by keep press button.
• It is a wireless module. So do not use it in an environment with signal interference.
• The display can only show for 5 seconds and then enter to power saving mode.
• There is a SMD component so that you can place it on PCB and then fix by tin.
