DC 4.5V-5.5V DIY Digital FM 2W 8ohm Speaker Electronics Kit/Finished

Features:
With power-off memory function
Introduce the power-saving function: After each power-on or press the FM key, the digital tube displays the frequency for 5 seconds. After 5 seconds, the digital tube display will be automatically turned off. There are two reasons for this design. 1 is power saving, and 2 is the digital tube. Disturbing sound when displayed, turning off the digital tube monitor, the sound is more beautiful.
