Produktbeschreibung

Matters needing attention
1: The power supply voltage of this module is 3.5-5V, pay attention to the power supply voltage in this range, too high voltage will burn the module.
In order to reduce the noise caused by the common ground, the module AGND needs an independent wire connected to the main filter capacitor of the power supply
The ground or connect to the power amplifier AGND.
2: Place the external 10V/100uF electrolytic capacitor as close as possible to the power pin of the module
Good for better filtering effect.
3: Bluetooth works in the 2.4G band, it is recommended not to place too close to the wireless router, so as not to preemption each other
The connection stability is reduced.
4.2 4G Bluetooth signal can not pass through the metal, the product is applied to the metal shell requires an external antenna, antenna selection
2.4G band IPX1 interface.
6: When applied to product PCB wiring, do not line the module PCB antenna below, do not apply copper foil, you should know
The concept that channel signals cannot penetrate metal is extremely important to ensure communication distance.
The external capacitor C1(10V/100uF) is the filter capacitor of the module, which must be connected, cannot be saved, and is not connected to the ground
Square or no connection with 100% bottom noise.
Pin 8 AGND (audio) as shown in the figure to pull a separate wire to the power supply (battery or DC power supply)
At the negative electrode of AGND, there is 100% super noise + distortion if it is not connected correctly or not connected
