Features:

- LED dot matrix module display time, temperature, date, week and other information;

- 8 different spectrum effects

- 7 different clock effects

- 8 levels of brightness adjustment function, built-in photoresistor, can automatically adjust the brightness according to ambient light, can also specify the brightness;

- with LED driver TM1640 Passive buzzer

- with Acrylic shell;

- Overall size: 220mm x 70mm x 28mm;

Note:

- Power supply: DC 5V voltage, can use computer or mobile phone charger power supply, pay attention not to use power supply higher than 5V, otherwise it will burn out

- In spectrum mode, if the audio cable is not connected to the mobile phone or computer, it is prone to interference

- In spectrum mode, the volume should be more than 50% as far as possible, otherwise the volume will be too low to distinguish

- In the menu setting, gain is the spectrum gain. If the spectrum jitter is too low, the gain can be adjusted up (or the volume can be adjusted up). If the spectrum is full, the gain can be adjusted down (or the volume can be adjusted down)
