Board size: 7.7 x 6.1cm
Operating voltage: DC 4.5V-5.5V
DC power supply, inside positive outside negative, do not connect reverse
FM range: 87MHZ-108MHZ
FM step: Click once step 0.1MHZ, long press FM button can add and subtract continuously
Function: Digital display frequency function, power off memory function, power saving function
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
