Instructions for use:
1. The positive and negative poles of the power supply need to be connected correctly. Use 5V for power supply. The capacitor must be connected to the VCC and GND of the module (the lead wire should be as short as possible, the long pin should be connected to VCC, and the short pin should be connected to GND), which will play a certain role in reducing noise and current sound. .
2. Because this current is very small, the power supply cannot use a power bank or other high-current power adapter.
3. The module will automatically start after power-on, the mode is AUX input, and the LED flashes.4. When the Bluetooth audio device is connected, the mode will automatically switch to Bluetooth mode, and the LED will be on for a long time.
5. EN pin, output high level (+3.3V) after Bluetooth is connected. 6. In order to make the sound quality better, this product is not designed with a telephone call function. - Renaming a KRC-86B Bluetooth Module
