After the module is connected to Bluetooth, Bluetooth wireless transmission can be quickly realized, which is very convenient. The module interface is a half-hole process that allows the customer to attach directly or solder to  the board. In an open environment, the Bluetooth connection distance can be up to 20 meters.\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/h1\u003e\n\n\u003cdiv style='box-sizing: content-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; padding: 0px; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; font-family: \"Open Sans\", sans-serif; color: rgb(0, 0, 0);'\u003e\n\u003cp style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; font-size: 14px; line-height: inherit; font-weight: 400; padding: 0px;\"\u003e\u003cspan style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; padding: 0px; max-width: 100%; word-break: break-word; font-size: 12px;\"\u003e\u003cspan style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; padding: 0px; max-width: 100%; word-break: break-word; color: rgb(0, 32, 96);\"\u003e\u003cspan style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; padding: 0px; max-width: 100%; word-break: break-word; font-size: 16px;\"\u003e3. Function \/Pin definition\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; font-size: 14px; line-height: inherit; font-weight: 400; padding: 0px;\"\u003e\u003cspan style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; padding: 0px; max-width: 100%; word-break: break-word; font-size: 12px;\"\u003e\u003cspan style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; padding: 0px; max-width: 100%; word-break: break-word; color: rgb(0, 32, 96);\"\u003e\u003cspan style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; padding: 0px; max-width: 100%; word-break: break-word; font-size: 16px;\"\u003e1 .

Current sound: The cause is ground wire interference. It is recommended that the output of the Bluetooth module should not be plugged in. It is necessary to weld the wire, especially the ground wire, and the wire should not be too long. The shorter the better, the thicker.  The problem of audio grounding at the grounding point of the power amplifier board must be connected to the ground of the audio input of the power amplifier. This grounding point can be tried to solder at different positions to achieve the lowest current sound. It is recommended that the Bluetooth and the power amplifier board be powered separately to isolate the Bluetooth ground and the amplifier ground.\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; font-size: 14px; line-height: inherit; font-weight: 400; padding: 0px;\"\u003e\u003cspan style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; padding: 0px; max-width: 100%; word-break: break-word;\"\u003e\u003cspan style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; padding: 0px; max-width: 100%; word-break: break-word; color: rgb(0, 32, 96);\"\u003e\u003cspan style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; padding: 0px; max-width: 100%; word-break: break-word; font-size: 16px;\"\u003e2.\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; font-size: 14px; line-height: inherit; font-weight: 400; padding: 0px;\"\u003e\u003cspan style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; padding: 0px; max-width: 100%; word-break: break-word; font-size: 12px;\"\u003e\u003cspan style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; padding: 0px; max-width: 100%; word-break: break-word; color: rgb(0, 32, 96);\"\u003e\u003cspan style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0px; padding: 0px; max-width: 100%; word-break: break-word; font-size: 16px;\"\u003e3.2, signal interference: Bluetooth antenna is extremely vulnerable to high frequency or strong electromagnetic signal interference, try to place away from the place where the wireless device is sent.
