Features
1.Stable performance, strong signal acceptance, straight line distance 15 meters.
2. Input voltage support DC5-24V, can also be powered by lithium batteries or DC power supply, the higher the current, the more adequate output power.
3. High output power, single-board peak power 100W, TWS two-board peak power 100W + 100W.
4. Easy to use, Bluetooth amplifier connected to the power supply and speakers can be used, wireless transmission, high-fidelity sound quality.
5. Using the original chip, PBTL mode output, in PBTL mode configured as a 100W Class D mono audio amplifier, in the current enough scenarios, you can promote 2Ω 100W speakers.

Specification
Chip: TPA3116
Input voltage: DC 5-24V
Output power: single-board peak power 100W, TWS two boards connected peak power 100W + 100W
Power supply: lithium battery or DC power supply (the higher the current, the more sufficient output power.)
Effective communication distance: 15 meters in a straight line
Bluetooth Name: BT-TWS
Size: 40x35x15mm
Applications: Bluetooth stereo, toys, massage chairs, household appliances, electric cars, lighting, photovoltaic products, fitness equipment and so on.
Note: There will be enough power output only when the supply voltage/current is enough. Higher supply voltage relative output power will be larger, different impedance speakers will have different output power, in the case of voltage and current enough, the larger the speaker Ω number. The smaller the relative output power is the smaller.

Warm reminder:
* Supports two boards to connect, you can buy two to use together.
* TWS pairing method, bluetooth board on the power, the two boards will be automatically paired, about 15 seconds after the pairing success and then open the cell phone bluetooth connection can be.
* Please make sure that this board meets your needs before purchase, you need another speaker and power supply to match complete.
* This link is only the board, there is no cable delivered by default; speakers and batteries we do not provide.
* Speaker standard is 4Ω 50W-100W.
* Avoid installing in metal sealed space, it will affect the bluetooth signal reception resulting in intermittent sound or no sound.
* Pay attention to the positive and negative poles when wiring the power supply! Please use in the calibrated voltage range, wrong connection and too high voltage will burn the board, too low will not work.
