Note:
1. Use the power amplifier board as far away as possible from the WIFI signal (router)
2. The recommended supply voltage is DC 8~24V, if it exceeds 26V, the chip will burn.
3. The power supply does not exceed 12V when connected to a 4Ω speaker, and does not exceed 24V when connected to an 8Ω speaker
4. The power supply current is recommended to be above 2A.
5. The working power of the module exceeds 20W*2, and a heat sink is required
6. The speaker cable should not be too long, and ensure that it is suitable within 1 meter
7. Pay attention to static electricity protection. Discharge the static electricity on your hands before touching the power amplifier board to prevent static electricity from breaking down the chip. Bluetooth chips are more sensitive to static electricity.
8. It is recommended to adapt the speaker with a rated power of 30W and above to avoid the speaker from heating and burning
