3.7V Bluetooth Audio Module Mono/Stereo Bluetooth Receiver module

Catatan : Kapasitor yg dikirim bisa tidak persis seperti gambar. Voltage : 3.7V 5V : https://www.tokopedia.com/lisuinstrument/bluetooth-audio-module-mono-stereo-bluetooth-receiver-module-5v Perhatian : Kebetulan PCB untuk kedua model sama. Untuk tipe 3.7V ini nantinya diboard tertulis 5V. Perbedaannya pada 5V di kiri atas itu diode 4148 T4 sementar versi 3.7V resistro 0ohm. Terkait: https://www.tokopedia.com/lisuinstrument/stereo-4-2-bluetooth-amplifier-module-5w-5w-w-micro-usb-charging-port LED connection status: - Fast blinking : not paired - Full : paired - Slow blinking: paired dan menerima data audio Capacitors : They eliminate the DC component generated by the module which is around 1.4 volts per channel. Dropping that kind of voltage on a low impedance input - say your regular headphones - would draw too much current for the module. Constant heat will be generated both on the module side and in the speakers prematurely shortening their lives.

Among them, the LED status port is connected with a 100 ohm resistor in series. The LED indicates that the Bluetooth is not connected and the flash is fast. After Bluetooth connection is successful, it is slow flashing.
