Supply voltage: DC 12V to 24V
Output power: 80W X 2
Power efficiency > 90%
Number of channels: double channel output
Size: 60*32*14mm (length*width*height)
Weight: about 40g
 
TPA3116D2 chip features:
 
1. High-efficiency class D operation, with > 90% power efficiency and low idle loss characteristics, advanced modulation system configuration, multiple switching frequencies, and AM interference prevention;
2. The TPA3116D2 advanced oscillator / PLL circuit uses multiple switching frequency options to suppress AM interference. When used with the master-slave mode option, multiple devices can also be synchronized;
3. The TPA3116D2 device provides comprehensive protection against short circuit, overheating, overvoltage, undervoltage and DC faults. In the event of an overload condition, the device reports the fault condition to the processor, thereby avoiding its own damage.
 
Note:
 
The general power supply and power amplifier should be kept at a certain distance to avoid electromagnetic interference. It is better to use a high quality power supply and the power supply will be stable. If you use a power supply such as a transformer, it is best to cover the transformer with a metal cover to prevent electromagnetic interference.
 
 
 
 

Never hunt around for another crystal again, with the Si5351A clock generator breakout This chip has a precision 25MHz crystal reference and internal PLL and dividers so it can generate just about any frequency, from <8KHz up to 150 MHz.
 
The Si5351A clock generator is an I2C controller clock generator. It uses the onboard precision clock to drive multiple PLL's and clock dividers using I2C instructions. By setting up the PLL and dividers you can create precise and arbitrary frequencies. There are three independent outputs, and each one can have a different frequency. Outputs are 3Vpp, either through a breadboard-friendly header or, for RF work, an optional SMA connector.
 
We put this handy little chip onto it's own breakout board PCB, with a 3.3V LDO regulator so it can be powered from 3-5VDC. We also put level shifting circuitry on the I2C lines so you can use this chip safely with 3V or 5V logic.

Connecting as the following picture.
Physical display
NOTE:
1.        Keep 2 meters away from router to avoid WIFI interference
2.        8~24VDC is recommended; upper than 26V, it will be damaged.
3.        Driving 4 load, power supply must be under 12V; and driving 8 load, supply must be under 24V.
4.        The supply current must be 2A at least.
5.        If the module works upper 20W x 2, a cooling fin will be needed.
6.        The line connecting speaker with module should be within one meter.
7.        ESD protection, please release ESD on your hands before you contact the module.
8.        30W and upper power speakers is recommended.
Fault Check
1. Check the power supply if the LED is not bright.
2. If the LED is on, but Bluetooth device XY-P15Wis not searched, check if the router is in the near, and keep away from the router.
3. The speaker tapped when power on.
1)   Check that the speaker load is so small that the current through the speaker is enough for chip goes into DC protection. Try to lower the supply and restart.
2)   Check that if the power supply is low that cannot drive the speaker. 2A power supply current is ok.
4. Floor noise in speaker when playing
1)   Play another music to verify the noise is not related with music itself.
2)   Replace the speaker to check If the noise is caused by speaker itself.
3)   Replace the power supply to check If the noise is caused by unstable power.
5. It plays intermittently
1)    Check if the temperature of the board is high, and it goes into thermal protection.
2)    Check if the Bluetooth is unstable, adjust the angle between the connected device; And Check if a WIFI source is in the near.
