Description:

• It is a FM MW SW Wireless Radio Receiver Module with built-in Mono dual channel 4ohm 5W Amplifier so that it can connect speaker directly.

• It supports FM 87-108MHz, MW 522-1620KHz, SW 4.75-21.85MHz optional working frequency. So user just needs connect work voltage and speaker or headset.

• It is also a high-sensitivity digital clock controlled radio set that integrates FM, AM and SW three bands. - It adopts a modular structure of splicing installation, which is very suitable for radio electronics enthusiasts, electronic DIY enthusiasts and primary and secondary school students to exercise their hands-on ability. The circuit modules are connected by connectors.

• The installation process can be completed only by preparing a screwdriver and referring to the installation manual. A high sensitivity digital radio can be assembled without using an electric soldering iron.

Features:

• FM/MW/SW Frequency: It is a radio set integrating FM, MW, SW within different frequency ranges. FM is 87-108MHz, MW is 522-1620KHz, SW is 4.75-21.85MHz. Note: MW adopts AM mode. Search and automatically save stations.Continue to play the last radio station when turn ON again.

• Mono 5W Amplifier: Built-in power amplifier which can drive mono 4ohm 5W speakers directly and the sound is very clear. User also can connect headset from AUX audio output socket.

• Time/Automatic Startup: Clock and radio functions can be switched. The time can be calibrated and the timing boot time can be set.

• Rechargeable: It is powered by 3.7v polymer lithium battery which can be used as outdoor mobile speaker. Built-in charging module is also more convenient for battery charging. At the same time, the power indicator shows the battery capacity in real time.Backlight enters power-saving mode after 10 seconds.

• DIY Electronic Soldering Project. 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 handmade skills, but also increase the interest in electronic technology. Great for electronics hobbyists, beginners, school and home education.
